Question 189364


We have two people that I will call person A and person B.

Because they are riding toward each other, times equal total distance given.

Person A:

time on bike = 4 hours

speed = x

distance = 80 miles

=====================

Person B:

time on bike = 4 hours

speed = (1.5 + x)

distance = 80 miles

=======================

4x + 4(1.5 + x) = 80 miles

Can you solve for x now?

When you find the answer for x, you will know the speed of Person A.
To find the speed of Person B, replace x in the expression (1.5 + x) with the value you find for x.  

Understand?
