Question

Deandre throws his fastball 99 miles per hour. If he starts 60 feet, 6 inches from home plate, how many seconds does it take the ball to get to the plate?

Answer 1

0.42 seconds

Explanation:

sped of fastball: 99 mi / hour = 99 x 63360 inches / 3600 sec = 1742.4 inches/sec

distance: 60 ft 6 inches = 60 x 12 + 6 = 726 inches

Ball travel time: (726 inches) / (1742.4 inches/sec) = 0.42 seconds
