  1. RATE-TIME-DISTANCE PROBLEMS

  2. 1. A river boat paddled upstream at 12 km/h, stopped for 2 hours of sightseeing, and paddled back at 18 km/h. How far upstream did the boat travel if the total time for the trip, including the stop, was 7 hours?

  3. 2. Pam jogged up a hill at 6 km/h and then jogged back down at 10 km/h. How many kilometers did she travel in all if her total jogging time was 1 hours and 20 minutes?

  4. 3. Sharon drove for part of a 150 km trip at 45 km/h and the rest of the trip at 75 km/h. How far did she drive at each speed if the entire trip took her 2 hours and 40 minutes?

  5. 4. An elevator went from the bottom to the top of a tower at an average speed of 4 m/s, remained at the top for 90 seconds, and then returned to the bottom at 5 m/s. If the total elapsed time was 4.5 minutes, how high is the tower?
