A person drove 30 miles per hour on a trip. If he had driven 45 miles per hour, he would have arrived 4 hours earlier. What was the distance the person drove?

Answer:D= 60miles
Step-by-step explanation:
Speed=distance/time
Distance = speed× time
D=(45-30)× 4
D= 15×4
D= 60miles
So you first make an expression by stating that in 45mi/hr you could have gone less than 4hrs. So then you set up proportions to solve for x, but x turns into miles. So that is the distance for the destination.
