Question

Two cyclists, 50 miles apart, start riding toward each other at the same time. One cycles 4 times as fast as the other, and they meet after 2 hours of riding. a. Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r r to represent the speed of the slower cyclist?

Answer 1

Answer:speed of slower cyclist is 5 mph

Step-by-step explanation:

Given

Distance between two cyclist is 50 miles

One cycle is 4 times fast as other

Speed of slower cyclist is r miles per hour

speed of faster cyclist is 4 r

they meet after t=2 hr

Distance traveled by fast cyclist is
`x=2* 4r`

Distance traveled by slower cyclist is
`y=2* r`

`x+y=50`

`2* 4r+2* r=50`

`8r+2r=50`

`10r=50`

`r=5 mph`

`4 r=20 mph`

speed of slower cyclist is 5 miles per hour
