Save

If the downstream speed of a boat is 15 km/hr and the speed of the stream is 2 km/hr, what is the speed of the boat in still water?

Detailed Solution: Question 1

Speed of the boat in still water = 15 – 2 = 13 km/hr
Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 3
Save

If 60% of the downstream speed of a boat is the same as the upstream speed of the boat. The speed of stream is what percentage of the speed of the boat in still water?

Detailed Solution: Question 3

60% of downstream speed = Upstream speed
Downstream speed : Upstream speed = 100 : 60 = 5 : 3
Stream speed : Speed of the boat in still water 

Hence, Option B is correct.

MCQ: Boats and Streams - 1 - Question 4
Save

If the speed of a stream is 3 km/hr and the speed of a boat in still water is 14 km/hr, what is the upstream speed of the boat?

Detailed Solution: Question 4

Upstream speed of the boat = 14 – 3 = 11 km/hr
Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 5
Save

The time taken by a boat while covering a certain distance upstream is thrice the time taken by it while covering the same distance in still water. If the upstream speed is 6 km/hr, what is the downstream speed?

Detailed Solution: Question 5

Time → In still water : US = 1 : 3
Speed → In still water : US = 3 : 1
Speed → US : DS = 1 : (3 + 3 – 1) = 1 : 5

Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 6
Save

If the upstream speed of a boat is 12 km/hr and the speed of the stream is 12 km/hr, what is the downstream speed of the boat?

Detailed Solution: Question 6

Downstream speed of the boat = 12 + 12 × 2 = 36 km/hr
Hence, Option C is correct.

MCQ: Boats and Streams - 1 - Question 7
Save

If the speed of a boat in still water is 12 km/hr and the speed of the stream is 3 km/hr, in how many hours can it cover 75 km downstream?

Detailed Solution: Question 7

Downstream speed = 12 + 3 = 15 km/hr

Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 8
Save

A boat goes 90 km downstream in 3 hours and 120 km upstream in 6 hours. In how many hours can it go 180 km downstream and come back to the starting point?

Detailed Solution: Question 8


Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 9
Save

A boat goes 2 km along the stream in 6 minutes and 20 km against the stream in 4 hours. What is the speed of the boat in still water?

Speed of the boat in still water 

Hence, Option C is correct.

MCQ: Boats and Streams - 1 - Question 10
Save

A man goes 80 km downstream and returns to the starting point in a total of 6 hours. If the ratio of the upstream speed to the downstream speed is 1 : 5, what is the speed of the stream?

Detailed Solution: Question 10

Let the upstream speed = x km/hr
Downstream speed = 5x km/hr

96 = 6x
x = 16

Hence, Option C is correct.

MCQ: Boats and Streams - 1 - Question 11
Save

If the speed of a stream is 5 km/hr and the speed of a boat in still water is 15 km/hr, what is the downstream speed of the boat?

Detailed Solution: Question 11

Downstream speed of the boat = 15 + 5 = 20 km/hr
Hence, Option A is correct.

MCQ: Boats and Streams - 1 - Question 12
Save

If the speed of a boat in still water is 15 km/hr and the speed of the stream is 3 km/hr, how much downstream distance can it cover in 3 hours?

Detailed Solution: Question 12

Downstream speed = 15 + 3 = 18 km/hr
So the answer = 18 × 3 = 54 km
Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 13
Save

A boat travels 80 km downstream in 4 hours. If the speed of the stream is 5 km/hr, in how many hours can it travel 40 km upstream?

Detailed Solution: Question 13


Upstream speed = 20 – 5 × 2 = 10 km/hr

Hence, Option D is correct.

MCQ: Boats and Streams - 1 - Question 14
Save

The speed of a boat in still water is 15 km/hr. It covers 45 km upstream in 6 hours. What is the speed of the stream?

Upstream speed of the boat 

Speed of the stream = 15 – 7.50 = 7.50 km/hr
Hence, Option A is correct.

MCQ: Boats and Streams - 1 - Question 15
Save

A man can row 40 km downstream and return in a total of 7 hours. If the ratio of the upstream speed to the downstream speed is 2 : 5, what is the downstream speed?

Detailed Solution: Question 15

Let the upstream speed = 2x km/hr
Downstream speed = 5x km/hr

28 = 7x
x = 4
So the answer = 5 × 4 = 20 km/hr
Hence, Option A is correct.
