Sophie drove to the amusement park at a rate of 36 mph and arrived in 2.5 hours. How long will it take her to get home if Sophie drives 45 mph? I NEED IT DONE ASAP

Find how many miles she drove:

2.5 hours x 36 mph = 90 miles.

Divide total miles by speed to get time:

90 miles / 45 mph = 2 hours.

It will take her 2 hours.

2 hours

Step-by-step explanation:

distance = speed * time

Substitute in what we know

distance = 36 * 2.5 =90 miles

We find the total distance

distance = speed * time

Using the formula we know the distance and the speed for the return trip

90 miles = 45 mph * time

Divide each side by 45

90/45 = time

2 hours = time

whats the question?
