Distance=speed times time
speed=5mph=5
time=30mins=30/60hr=1/2hr
so
distance=speed times time
he will run 2.5 miles in 30 mins at the speed of 5mph
speed=5mph=5
time=30mins=30/60hr=1/2hr
so
distance=speed times time
he will run 2.5 miles in 30 mins at the speed of 5mph
Answer:
t = 1.09 s.
Explanation:
This is a one-dimensional kinematics question, so the equations of kinematics will be sufficient to solve the question.
This quadratic equation can be solved using determinant.
Of course, we will choose the positive time.
