A car traveling 80km/h is 120m behind a truck traveling 66km/h. How long will it take the car to reach the truck?
Two ants race across a table 57 cm long. One travels 4.14 cm/s and the other 3cm/s. when the first crosses the line, how far behind is the second one? Answer in cm.
the car is traveling 14km/hr faster than the truck
14km/hr * 1000m/km * 1hr/3600sec = 35/9 m/s
120m / 35/9m/s = 30.86 sec
