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:
2.335 miles/hr
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
