Distance Problems (2)( Week 48 Evaluation) 1. The length of a train is 105 meters. It is driven at the speed of 21 meters per second. How many seconds will it take for the train to pass a 189-meter long tunnel (from entering to completely exiting from the tunnel)? 2. Susan starts out at the starting point of a trail at 4 meters per second, and 4 seconds later Joe starts out at the same point at the speed of 5 meters per second. In how many seconds will Joe catch up with Susan? 3. Josh and Laura start together and race their bikes around a circular trial at constant speeds. It will take Josh 8 minutes to go 1 lap, and it will take Laura 6 minutes for a lap. How long will it take Laura to be exactly 1 lap ahead of Josh (in minutes)? 4. The length of a bridge is 690 meters. A train crossed the bridge at 300 meters per minute. It took the train 3.3 minutes to cross the bridge (from entering to completely exiting the bridge). What is the length of the train in meters? 5. Jane was riding her bike to school at 9 MPH. Exactly half way, she got a flat tire on her bike and had to walk to the school for the remaining distance. If she was able to walk at 1 MPH, what was her average speed (in MPH) for the entire trip from home to school? 6. Ed and Ben are biking around a round trail which is 10 miles long. Ed bikes at 11 mph and Ben bikes at 9 mph. If both start from the same place and ride in the same direction, how long (in hours) will it take for them to meet again? 7. Mary and Julia are biking around a round trail which is 6 miles long. Mary bikes at 9 mph and Julia bikes at 7 mph. If both start from the same place but ride to different directions, how many minutes will it take for them to meet again? 8. A train traveling at 40 miles per hour reaches a tunnel which is 9 times as long as the train. If the train takes minutes to completely clear the tunnel, how long is the train in miles? Express your answer as a fraction in lowest terms. 9. If Mary can bike 42 feet in 6 seconds, how many minutes will it take her to bike 1260 yards? 10. Kevin drove his car at 56 mph for the same number of hours as that David drove his car at 64 mph. If Kevin ended up driving 72 miles less than David, how many hours did they drive? |
