Afamily on vacation drives 123 miles in 2 hours, then gets stuck in traffic and goes 4 miles in the next 15 minutes . the remaining 191 miles of the trip take 3 3/4 hours. what was their average rate of speed to the nearest tenth of a mile per hour ?

The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.

Total distance traveled = 123 miles + 4 miles + 191 miles = 318 miles

Total time taken = 2 hours + 15 minutes + hours

= 2 hours + hour + hours

= hours

= hours

= 6 hours

Average speed = Total distance Total time

= mile per hour

= 53 mile per hour.
