The distance between the two cities is 7.25•100=725 because you multiply the scale distance by the scale.
The number hours is 725/50=14.5 hours because you divide the distance by 50 (the miles per hour).

Answer:

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 $4\frac{1}{2}=4.5$ hours.

Use formula:

$D=r\cdot t,$

where

D = distance

r = rate

t = time.

In your case,

D = 239.4 miles

t = 4.5 hours

Hence,

$239.4=4.5r\\ \\r=\dfrac{239.4}{4.5}=53.2\ mph$
