Question

The Smiths leave Indiana at 6:00 am to travel to Georgia. They stop for 4 breaks totaling 3 hours and stop to visit some friends in Tennessee for 2 hours. They arrive at their destination at 11:00 pm. While driving their average speed was 65 mph. How many miles did the Smiths travel on their trip?

Answer 1

It's 975 because they traveled for 17 hours and had stopped for 2 hours do 17-2=15, so 15×65=975

Answer 2

Answer: Hi, so the travel starts at 6:00 am, and ends at 11:00 pm, this is a difference of 17 hours of travel. And we know that there where 3 hours (in the 4 breaks) + 2 hours (when visiting their friends) in which the Smiths where stop.

So the amount of hours in "motion" is : 17 hours - 5 hours = 12 hours.

now we know how much time they're actually traveling, and knowing the average velocity we can multiply the velocity by the time and obtain the miles traveled.

this is: 65m/h *12h = 780 miles.

so in their trip, the smiths travelled 780 milles.
