Q:
# Mrs. Perez drove 33.75 miles in 3/4of an hour. What was the speed in miles per hour if this situation is represented by the equation d=rt?

Accepted Solution

A:

The speed was 45 miles per hour Step-by-step explanation:Mrs. Perez drove 33.75 miles in [tex]\frac{3}{4}[/tex] of an hourThis situation is represented by the equation d = r t, whered is the distance in milesr is the speed in mile per hourt is the time in hourWe need to find the speed in miles per hour∵ Mrs. Perez drove 33.75 miles in [tex]\frac{3}{4}[/tex] of an hour∴ d = 33.75 miles∴ t = [tex]\frac{3}{4}[/tex] hour∵ d = r tSubstitute the values of d and t in the rule above∴ 33.75 = r ( [tex]\frac{3}{4}[/tex] )- Multiply both sides by 4∴ 135 = r (3)- Divide both sides by 3∴ 45 = r∵ r represents the speed in miles per hour∴ The speed was 45 miles per hourThe speed was 45 miles per hour Learn more:You can learn more about the speed in brainly.com/question/1386181#LearnwithBrainly
