Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
This is the concept of speed, distance and time: Time taken before the cyclist are on the same sport will be found as follows: time=distance/(relative speed) distance=1800 km given that the cyclist will be riding towards the same side, then relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h thus time taken will be: time=1800/15 =120 hours
