When the fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr, then the dive lasted for 276.377 seconds
What is speed?
The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.
The mathematical expression for speed is given by
speed = total distance /Total time
As given in the problem The fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr
Total distance = 19.5 miles
Total time =?
average speed
By substituting respective values in the formula of speed
254 mi/hr = 19.5 miles/time
time = 19.5/254 hr
time = 0.0767716 hr
As we know 1 hr = 3600 seconds
0.0767716 hr = 0.0767716 ×3600 seconds
=276.377 seconds
Thus, the dive lasted for 276.377 seconds
