Mara's family is driving to her grandmothers' house. the family travels 239.4 miles between the hours of 9: 10 a. m. to 1: 40 p. m. write an equation that mara can use to determine their average rate of travel, r, rounded to the nearest mile per hour.

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

Hence,
