if a driver drives 40 miles in an hour, what is his ratio of miles to minutes, in lowest terms?

• ratio -

You're partly right. Now you have to reduce this to lowest terms.

40:60 = 4:6 = 2:3

• ratio -

At the same speed, how long would it take the driver to travel 60 miles? how would I find that answer?

• ratio -

One way to solve this is with a proportion.

Cross multiply and solve for x.

40/60 = 60/x

40x = 3600

x = 90 minutes = 1 1/2 hours
