Question

Two friends, 7 miles apart, start walking toward each other, and they meet in an hour. If one boy walks 1 mile farther in an hour than the other boy, how fast does each walk?

Answer 1

Explanation:

the distance one boy travels is 'x', you can set up an equation like this:

x + x + 1 = 7

2x +1 = 7

2x = 6

x = 3

So one boy walks 3 miles in one hour, and the other walks 4 miles in one hour.

Therefore, their speeds are 3 miles per hour and 4 miles per hour respectively.

Answer 2

So lets say the distance one boy travels is 'x', you can set up an equation like this:
x + x + 1 = 7
2x +1 = 7
2x = 6
x = 3
So one boy walks 3 miles in one hour, and the other walks 4 miles in one hour.
Therefore, their speeds are 3 miles per hour and 4 miles per hour respectively.
