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

Is 2cosx=cos2x ?<br>i have misinterrupted​
faltersainse [42]

no it isn't. 2cos(x) is 2 multiplied by cos(x), cos (2x) is cos(2 multiplied by x) meaning 2x is the angle you're taking the cosine of. if you want to know what cos(2x) look up the double angle rule.
