Question

MEDAL!

1) If a train travels at an average speed of 37 miles per hour, how much time will it take to go 814 miles? Show your work.

Answer 1

814/37

Answer 2

\[d = r\cdot t\] where r = rate, t = time, and d = distance.

We're given that r = 37 mi/hr , d = 814 miles.

rearrange your function to solve for time. \[ \frac{rt}{r} = \frac{d}{r}\]\[ t = \frac{d}{r}\] Now just plug in your values. \[t = \frac{814 \ mi.}{37 \frac{mi}{hr}}= \frac{814}{37} \ mi\cdot \frac{hr}{mi} = \frac{814}{37} hr\]
