Answer:

Give brainliest please! The answer is 53.2 mph

Step-by-step explanation:

Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.

1:40 p.m. is 13:40.

Thus, they traveled for

13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes

that is hours.

Use formula:

where

D = distance

r = rate

t = time.

In your case,

D = 239.4 miles

t = 4.5 hours

Evaluate the expression: 6x + 5 - 3y, when y = 3 and x = -2

frozen [14]

First you need to substitute x for -2 and y for 3 in the equation.
So it would be...
6(-2) + 5 - 3(3)
-12+5-9
Then your answer is -16.
Hope that helped!
