Question

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ?

Answer 1

Answer: 34.68 mile/min^2

Step-by-step explanation:

1 mile = 1609 meter

1 min = 60 s then squared will be 3600s

Mile/min^2 = 2.24

Give 15.5m/s^2

We multiply

15.5 by 2.24

= 34.68 mile/min^2

Answer 2

You have to use conversion units for this. For every 1 mile, there is an equivalent amount of 1,609 meters. For every 1 minute, there is an equivalent amount of 60 seconds. Using the dimensional analysis approach, the solution is as follows:

Acceleration = 15.5 m/s²*(1 mile/1,609 m)*(60 s/1 min)² = 34.68 miles/min²
