A tractor covers a distance of 240 kms in 6 hours on the first day, 360 kms in 8 hours on the second day and 450 kms in 6 hours on the third day. Find the average distance per hour covered by him in 3 days.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 52.5 kms
Distance covered on the first day = 240 km
Time taken on the first day = 6 hours
Distance covered on the second day = 360 km
Time taken on the second day = 8 hours
Distance covered on the third day = 450 km
Time taken on the third day = 6 hours
Average speed = Total distance/Total time
Total distance covered = 240 km + 360 km + 450 km = 1050 km
Total time taken = 6 hours + 8 hours + 6 hours = 20 hours
Average distance per hour = Total distance covered/Total time taken = 1050/20 = 52.5
