Barry's family drove 843 miles to see his grandparents. On the first day, they drove 483 mi. On the second day, how long did it take to reach his grandparents house if they averaged 60 mi/h

on the second day it took them 6 hours to get to their grandparents' house

Step-by-step explanation:

First we have to calculate how many miles they had to drive the second day

For this we have to subtract from the total miles the number of miles they drove the first day

843 mi - 483 mi = 360 mi

To calculate the time it takes we have to divide the distance it has to travel by the average velocity at which they travel

v = 60 mi/h

d = 360 mi

t = d/v

t = 360 (mi) / 60 (mi/h)

t = 6 h

on the second day it took them 6 hours to get to their grandparents' house
