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

Answer:
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
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.
