Question

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ? 1. 6.89 miles/min2 2. 31.8 miles/min2 3. 2.69 miles/min2 4. 1.15 miles/min2 5. 34.7 miles/min2 6. 1.49 miles/min2 7. 0.581 miles/min2

Answer 1

For this case we have to take into account the following conversions:
 $1 mile = 1609.34 meters 1 minute = 60 seconds$
 Let's first transform the expression to miles per seconds squared:
 $(15.5) * (1 / 1609.34) = 0.009631277 mi / s ^ 2$
 Then, we transform the result to miles per minute squared.
 We have then:
 $(0.009631277) * (60) ^ 2 = 34.7 mi / min ^ 2$
 Answer:
 the rate in miles/min^2 is:
 $34.7 mi / min ^ 2$
