Two cyclists, 80 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other. If they

vivado [14]

The speed of the faster cyclist will be 30 miles/hour.

Explanation

One cyclist is 3 times as fast as the other.

Lets assume that the speed of the slower cyclist is $x$ miles/hour.

So, the speed of the faster cyclist will be: $3x$ miles/hour.

They start riding toward each other at the same time and meet 2 hours later.

We know that, $Distance= speed*time$

So, the distance traveled by slower cyclist in 2 hours $= (x*2)miles= 2x$ miles and the distance traveled by faster cyclist $=(3x*2) miles = 6x$ miles.

Given that, they were 80 miles apart at the starting. So, the equation will be.....

$2x+6x=80\\ \\ 8x=80\\ \\ x=10$

So, the speed of the faster cyclist will be: (3×10)= 30 miles/hour.
