DISTANCE = RATE*TIME

DISTANCE = RATE*TIME. D = rt D = r(t) D = r x t. Solving for time (t). D = rt Divide by rate (r) to get time (t) by itself d/r = t Distance/rate = time. Solving for rate (speed). D = rt Divide by time (t) to get rate (r) by itself Distance/time = rate d/t = r. practice.

  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

  4. practice • 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?

  8. TRAVELING AT DIFFERENT RATES • A bus traveling at an average rate of 50 kilometers per hour made the trip to town in 6 hours. If it had traveled at 45 kilometers per hour, how many more minutes would it have taken to make the trip?

  9. TRAVELING IN DIFFERENT DIRECTIONS • A bus and a car leave the same place and traveled in opposite directions. If the bus is traveling at 50 mph and the car is traveling at 55 mph, in how many hours will they be 210 miles apart?

  10. GIVEN TOTAL TIME • John took a drive to town at an average rate of 40 mph. In the evening, he drove back at 30 mph. If he spent a total of 7 hours traveling, what is the distance traveled by John?
