The ratio between the speeds of two trains is 7:8.if second train runs...
Given:
Ratio of speeds of two trains = 7:8
Distance covered by second train = 400 km
Time taken by second train = 5 hours
To find:
Speed of first train
Solution:
Let the speeds of first and second trains be 7x and 8x respectively.
We know that distance = speed x time
Distance covered by second train = 8x * 5 = 40x
Given, distance covered by second train = 400 km
40x = 400
x = 10
Therefore, speed of first train = 7x = 7 * 10 = 70 km/h
Answer:
The speed of first train is 70 km/h.

The ratio between the speeds of two trains is 7:8.if second train runs...
Speed of the two trains= 7:8
Second Train Speed= 400 km in 5 hrs
so,
take: S1= speed of first train, S2= Speed of second train.
now, S2 = 400÷ 5 = 80
7/8 = S1/S2
S2 = 80
= 7/8 = S1/80
7 × 80 = 8×S1
560 = 8S1
S1 = 560/8 = 70 km
Second Train Speed= 400 km in 5 hrs
so,
take: S1= speed of first train, S2= Speed of second train.
now, S2 = 400÷ 5 = 80
7/8 = S1/S2
S2 = 80
= 7/8 = S1/80
7 × 80 = 8×S1
560 = 8S1
S1 = 560/8 = 70 km
