Answer:
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
Step-by-step explanation:
Given that:
Mr. Reed leaves 5 hours early.
Speed of Mr. Reed = 40 mph
Distance covered in 5 hours = 40 * 5 = 200 miles
Let,
h be the number of hours and D be the total distance.
D = 40h + 200
Speed of Mrs. Reed = 50 mph
D = 50h
For catching up, both distances will be same
D = D
50h = 40h + 200
50h - 40h = 200
10h = 200
Dividing both sides by 10
[tex]\frac{10h}{10}=\frac{200}{10}\\h=20[/tex]
Therefore,
It will take 20 hours for Mrs. Reed to catch up with Mr. Reed
