Answer:
The time taken for the rider to hit the valley floor is 6.22 seconds
Explanation:
The formula to be used here is that of speed
Speed = distance ÷ time
where speed is 30.7 m/s and distance is 191 m, time taken to hit the valley floor is the unknown; thus we solve for time (in seconds).
time = distance ÷ speed
time = 191 ÷ 30.7
time = 6.22 secs
The time taken for the rider to hit the valley floor is 6.22 seconds
