How do you solve distance rate time problems?

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.

What is d r * t?

We use the formula d = r * t, where d is the distance, r is the speed and t is time to solve the following problems. Example 1. A car travels 120 miles at the speed of 48 miles per hour. Find the time taken for the journey using the formula d = rt.

What is the formula for calculating speed?

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

How did you solve for distance?
