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
hours.
Use formula:
![D=r\cdot t,](https://tex.z-dn.net/?f=D%3Dr%5Ccdot%20t%2C)
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](https://tex.z-dn.net/?f=239.4%3D4.5r%5C%5C%20%5C%5Cr%3D%5Cdfrac%7B239.4%7D%7B4.5%7D%3D53.2%5C%20mph)
