The second friend runs at a speed of 7 miles per hour. If they left at 6 p.m. and their houses are 20 miles apart, at what time will they meet? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! The first friend runs at a speed of 8 miles per hour.
The second friend runs at a speed of 7 miles per hour.
they left at 6 p.m.
their houses are 20 miles apart,
Since they are running towards each other the effective speed will be (8+7) = 15 mph
Distance = 20 miles
time they run = 20/15 =4/3 hours
They meet at 7.20 pm
