Question

Yoshika drives at a constant speed and travels y miles in 37 minutes. What expression represents her constant speed in miles per minute?

Answer 1

Answer:

$\frac{Y}{37}$ miles per minute

Step-by-step explanation:

The formula to calculate average speed is:

$s=\frac{d}{t}$

where s is speed, d is distance, and t is time.

we know that she traveled 'Y' miles, so the distance is:

$D=Ymiles$

and she traveled that distance is 37 minutes, so the time is:

$t=37min$

and substituting this into the average speed equation:

$s=\frac{Ymiles}{37minutes} \\\\s=\frac{Y}{37}mi/min$

the average speesdis $\frac{Y}{37}$ miles per minute (mi/min)
