Answer:

1.2 hours, or 72 minutes

Step-by-step explanation:

If David drove for 1.5 hours at 36 mph, that means that he traveled a distance of (36*1.5) = 54 miles.

If he takes the same route at a speed of 45 mph instead, he will reach his destination in (54/45) = 1.2 hours, which is equivalent to 72 minutes.
