Yoshika drives at a constant speed and travels y miles in 37 minutes. What expression represents her constant speed in miles per
Svetlanka [38]

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)

Calculate for y given that mean of 20,2y,25,y,30 is 27​
masha68 [24]

Answer:

y = 218

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers present)

27 = (20 + 2y + 25 + y + 30)/27

27 = (3y + 75)/27

3y + 75 = 729

3y = 729 - 75

3y = 654

y = 218
