1. DISTANCE = RATE*TIME
D = rt
D = r(t)
D = r x t

2. Solving for time (t) D = rt
Divide by rate (r) to get time (t) by itself
d/r = t
Distance/rate = time

3. Solving for rate (speed)
D = rt
Divide by time (t) to get rate (r) by itself
Distance/time = rate
d/t = r

Now let's say you rode your bike at a rate of 10 miles per hour for 4 hours. How many miles did you travel?

5. practice
Let's say you rode your bike 2 hours and traveled 24 miles. What is your rate of speed?

6. practice
Next, you ride 18 miles and travel at a rate of 12 miles per hour. How long did this take you?

7. practice
James and Javier each go on separate trips with Javier driving twice as fast as James. James travels for 3 hours while Javier travels for 2 hours. They drive a total of 280 miles. How fast does Javier drive?
