Question

Jimmy and his family  are  on their way to visit some family friends who live

Answer 1

Answer:

The hours it take to reach their family's friend home is 2.5 hours

Step-by-step explanation:

The distance the family is expected to cover is 780 miles.  They expected to cover that distance within 3 days. Let us divide the trip into 3 sections.

Day 1

speed = distance/time

time = 4 hrs

speed = 60 miles per hr

distance = speed × time = 4 × 60 = 240 miles

Day 2

speed = distance/time

time = 6 hrs

speed = 65 miles per hr

distance = speed × time = 6 × 65 = 390 miles

Day 3

speed = distance/time

time = ?

speed = 60 miles per hr

distance = 780 - 240 - 390 = 150  miles

time  = distance/speed

time = 150/60

time = 2.5

The hours it take to reach their family's friend home is 2.5 hours

Answer 2

It will take 2 and a half hours
