The Roberts family is taking a road trip. They plan to drive 1500 miles over two days, stopping for the night when they are halfway. How many hours will they drive for the first day if they average 50 mph over the course of the trip? Explain:

The number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours

Step-by-step explanation:

The given parameters are;

The distance the Roberts family plan to drive = 1500 miles

The average speed at which they drove = 50 mph

We note that the formula for average speed = Total distance/(time)

Therefore, we have;

50 mph = 1500 miles/(time, t)

Time = 1500 miles/(50 mph) = 30 hours

Given that for the first day of the 2 days, they will cover half their total distance, which is 1500 m/2 = 750 m

The time taken = 750 miles/(50 mph) = 15 hours

The time take to cover half the distance = 15 hours

Therefore, the number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours.
