Answer:
90 minutes
Step-by-step explanation:
We know that distance = rate * time
We know the distance and the rate, and need to find the time
distance = 60 miles
rate = 40 mile per hour
60 = 40 * t
Divide each side by 40
60/40 = 40t/40
1.5 = t
1.5 hours
Now we need to change it to minutes
1.5 hours * 60 minutes/1 hours = 90 minutes
