Question

What is the average speed in kilometers per hour if you travel 194 kilometers in 4.1 hours?

Answer 1

47.317 or about 47.32kph is the average speed.

You could set this up as a standard ratio to help visualize how to solve this problem. For every 194 kilometers, 4.1 hours has passed in meaning the ratio would be 194:4.1. Next find what side would make 4.1 would change into 1 so you would do 4.1 divided by 4.1 which will give you 194:1. But with a ratio you need to divide on both sides of the ratio. So do 194/4.1 which would equal to about 47.317.
