Two motorbikes Z and X are 777 meters apart. They both start running separately in the same direction with speeds of 72 m/sec & 35 m/sec respectively. In how much time will Z overtake X? |
33 sec 22 sec 21 sec 15 sec |
21 sec |
Relative speed = 72 m/s - 35 m/s = 37 m/s Time = \(\frac{Distance}{Relative speed}\) = \(\frac{777}{37}\) = 21 seconds |
