Question 629728: on saturday ,earl rode his bike for two hours longer than ted. earl traveled 135 km and tes traveled 81 km if they both averaged the same rate of speed how long did earl ride Answer by solver91311(24713) (Show Source):
Subtract 81 from 135. That is the distance that the first guy traveled during the two hours he was riding when the other guy wasn't riding. Distance equals rate times time, so rate must equal distance divided by time. The result of your first calculation divided by 2 hours is the rate of speed for both of them. Now you need to know the time it took either of them to go the remaining 81 km. Divide distance (81 km) by the calculated rate. Add the time it took the guy to go the first part of the trip (2 hours) to the time calculated to go the remaining distance to get the total time the first guy traveled.
