To find out how long it will take David to drive home at 45mph, we can use the formula:
time = distance / speed
Since the distance remains the same for both trips, we can calculate the time it will take for David to drive home at 45mph by using the time it took him to reach camp at 36mph.
Time to reach camp at 36mph = 1.5 hours
Distance = speed * time
Distance = 36mph * 1.5 hours
Distance = 54 miles
Now, we can calculate the time it will take for David to drive home at 45mph.
Time = Distance / Speed
Time = 54 miles / 45 mph
Time = 1.2 hours
Therefore, it will take David 1.2 hours (or 1 hour and 12 minutes) to drive home if he takes the same route and drives at 45mph.
David drove 36mph and reached camp in 1.5 hours. How long will it take him to drive home if he takes the same route and drives 45mph?
