Question

You walk 2 miles in 1/2 hour. At that rate, how long will it take you to walk 3 miles?

figure out the speed by dividing distance by time, then divide that by the distance to be covered to get the time. :)

Answer 2

Get it in terms of miles per hour, and then set up a ratio and cross multiply and divide.
