Solving for rate and time. In the problem we just solved we calculated for distance, but you can use the d = rt formula to solve for rate and time too. For example, take a look at this problem: After work, Janae walked in her neighborhood for a half hour. She walked a mile-and-a-half total.
Convert minutes into fractions of an hour first. 6 minutes =6/60 or 1/10 hour to run 1 mile. 8 minutes =8/60 or 2/15 hour to run 1 mile. Convert the time to rum 1 mile into miles per hour by multiplying it by a quantity which turns the time into 1 hour. This quantity is then equivalent to the miles run in 1 hour, or miles per hour.

The formula for distance problems is: distance = rate × time or. d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
