Convert 7.7km into miles if 1.6 km = 1 mile

Lemur [1.5K]

This is a simple equation.

The equation is y = 1.6x with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 * 7.7 = 12.32

12.32 miles is equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 = 4.8

In this case there are 4.8 miles in 7.7 kilometers
