If two people are trying to meet and the distance between them are 12 miles apart how long does it take them to meet each other. one person walks 5 miles in 1 hour and the other person walks 3 miles in a hour

Person a can walk 5 miles in an hour.
Person b can walk 3 miles in an hour.
They are 12 miles apart, and after an hour they have covered 8 miles.

8:1 = 12:x

8x = 12

x = 1.5

After an hour and a half, they will meet.

Check:
5 miles : 1 hour = 7.5 miles : 1.5 hours

3 miles : 1 hour = 4.5 miles : 1.5 hours

Together, they should have covered 12 miles.
7.5 + 4.5 = 12

It takes 1.5 hours to meet eachother.
