Total time taken by Sam before Al caught up with him = 15+10 = 25 minutes

In hours = 25 minutes = 25/60 = 5/12 hrs
Distance covered by Sam = Distance covered by Al = Speed (Sam) * time taken = 3.2*5/12 = 4/3 miles.

Al takes 10 minutes to cover that distance. Therefore,
Al's speed = Distance/time = (4/3)/(10/60) = (4/3)*(60/10) = 8 mph

Patty measured the elementary school and made a scale drawing. The scale she used was 7 centimeters = 1 meter
Verdich [7]

Write the scale of the drawing as a fraction. Put the shorter length in the numerator.

\frac{7 \: cm}{1 \: cm}  \\

First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.

\frac{7 \: cm}{100 \: cm}  =  \:  \frac{7}{100}  \\

Write the scale factor as a ratio, using a colon

7/100   →  7:100

The scale factor is 7:100.
