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