View all questions of this test
Total time= 8 hours
Time to go to the spot = 4 hours
Time to return = 4 hours
Average speed while going = 40 mph
Average speed while returning = 30 mph
Therefore
max distance while going = 4 � 40 m
= 160 m
max distance while returning =4 �30 m
= 120 m
Therefore
max distance he can select a picnic spot will be the least distance between max distance while going and coming
i.e., 120 m
Ans:- 120m

Given information:
- A person should not exceed 8 hours of driving in a day for a weekend trip
- Average speed of forward journey = 40 mph
- Average speed of return journey (on Sundays) = 30 mph
To find: How far he can select a picnic spot
Approach:
Let's assume the person drives for 'x' hours for the forward journey.
Then, he will also drive for '8 - x' hours for the return journey.
Using the formula: Distance = Speed x Time, we can find the distance covered by the person in each journey.
Calculation:
Distance of forward journey = 40x
Distance of return journey = 30(8 - x) = 240 - 30x
Total distance covered in the trip = Distance of forward journey + Distance of return journey
= 40x + 240 - 30x
= 10x + 240
As the person should not exceed 8 hours of driving, we can assume x ≤ 8.
Now, we need to find the maximum possible value of (10x + 240) for x ≤ 8.
By substituting x = 8, we get:
Total distance covered in the trip = 10(8) + 240 = 320 miles
By substituting x = 7, we get:
Total distance covered in the trip = 10(7) + 240 = 310 miles
By substituting x = 6, we get:
Total distance covered in the trip = 10(6) + 240 = 300 miles
By substituting x = 5, we get:
Total distance covered in the trip = 10(5) + 240 = 250 miles
By substituting x = 4, we get:
Total distance covered in the trip = 10(4) + 240 = 240 miles
As the person should not exceed 8 hours of driving, the maximum distance he can select a picnic spot is 120 miles (when he drives for 4 hours for the forward journey).
Therefore, the correct answer is option A) 120 miles.
- A person should not exceed 8 hours of driving in a day for a weekend trip
- Average speed of forward journey = 40 mph
- Average speed of return journey (on Sundays) = 30 mph
To find: How far he can select a picnic spot
Approach:
Let's assume the person drives for 'x' hours for the forward journey.
Then, he will also drive for '8 - x' hours for the return journey.
Using the formula: Distance = Speed x Time, we can find the distance covered by the person in each journey.
Calculation:
Distance of forward journey = 40x
Distance of return journey = 30(8 - x) = 240 - 30x
Total distance covered in the trip = Distance of forward journey + Distance of return journey
= 40x + 240 - 30x
= 10x + 240
As the person should not exceed 8 hours of driving, we can assume x ≤ 8.
Now, we need to find the maximum possible value of (10x + 240) for x ≤ 8.
By substituting x = 8, we get:
Total distance covered in the trip = 10(8) + 240 = 320 miles
By substituting x = 7, we get:
Total distance covered in the trip = 10(7) + 240 = 310 miles

Total distance covered in the trip = 10(6) + 240 = 300 miles

Total distance covered in the trip = 10(5) + 240 = 250 miles
By substituting x = 4, we get:
Total distance covered in the trip = 10(4) + 240 = 240 miles
As the person should not exceed 8 hours of driving, the maximum distance he can select a picnic spot is 120 miles (when he drives for 4 hours for the forward journey).
Therefore, the correct answer is option A) 120 miles.
