Distance Problems (2)( Week 48 Evaluation) 1. The length of a train is 115 meters. It is driven at the speed of 23 meters per second. How many seconds will it take for the train to pass a 161-meter long tunnel (from entering to completely exiting from the tunnel)? 2. Nancy starts out at the starting point of a trail at 5 meters per second, and 1 seconds later George starts out at the same point at the speed of 6 meters per second. In how many seconds will George catch up with Nancy? 3. Smith and Anne start together and race their bikes around a circular trial at constant speeds. It will take Smith 6 minutes to go 1 lap, and it will take Anne 4 minutes for a lap. How long will it take Anne to be exactly 1 lap ahead of Smith (in minutes)? 4. The length of a bridge is 1670 meters. A train crossed the bridge at 450 meters per minute. It took the train 4.6 minutes to cross the bridge (from entering to completely exiting the bridge). What is the length of the train in meters? 5. Sofia was riding her bike to school at 7 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 3 MPH, what was her average speed (in MPH) for the entire trip from home to school? 6. Josh and Rene are biking around a round trail which is 6 miles long. Josh bikes at 10 mph and Rene bikes at 8 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. Helen and Emily are biking around a round trail which is 8 miles long. Helen bikes at 11 mph and Emily bikes at 5 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 5 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 Hillary can bike 56 feet in 8 seconds, how many minutes will it take her to bike 2100 yards? 10. Josh drove his car at 56 mph for the same number of hours as that Rene drove his car at 65 mph. If Josh ended up driving 45 miles less than Rene, how many hours did they drive? |
