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

Is the answer 40:60?

  • 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

  • ratio - ,
