Question

David Huxley holds the world record for heaviest plane pulled. The plane weighed 184 tons. He covered 91m in 1 min and 27 sec. How many miles per hour did he average while moving the plane?

Answer 1

2.335 miles/hr

Step-by-step explanation:

The distance he covered = 91 m

the time he spent pulling the weight = 1 min 27 sec

1 m = 0.000621371 mile

91 mile = 91 x 0.000621371 = 0.0565 miles

1 min = 60 sec

therefore 1 min 27 sec = 60 + 27 = 87 sec

3600 sec = 1 hr

87 sec = 87/3600 = 0.0242 hr

speed = distance/time

speed = 0.0565 miles / 0.0242 hr = 2.335 miles/hr
