Travis will complete a 60-mile trip in _____ hours?
Natasha2012 [34]

Answer:  2.5 hours is the answer

Step-by-step explanation:

It took Travis 2.5 hours to complete 3/4 of his trip. To find the average speed, we need to find his speed during 3/4 of the trip and then the 52.5 miles. 

So you know that 52.5 is 1/4 of his total trip. That means if we multiply that by 3, that's how many miles he traveled in 2.5hrs. (157.5)

To calculate speed, divide distance by time. 

For 3/4 of his trip (157.5), it took him 2.5 hours. 

157.5/2.5 = 63mph

For the remaining 52.5 miles, it took him an hour.

52.5/1 = 52.5mph

Now average those two speeds to get the average speed for the whole trip.

(63+52.5)/2= 57.6mph
