The cyclist rode for 4 hours at a speed of 20 km / h, and a motorcyclist for 3 hours at a speed of 70 km / s. How far have they covered together during this time?
1. From the condition of the problem it follows that the speed of the cyclist is 20 km / h and he traveled for 4 hours, and the speed of the motorcyclist is 70 km / h and he traveled for 3 hours.
2. The distance covered is calculated as the product of speed and time, which means that the cyclist traveled 20 * 4 = 80 km, and the motorcyclist traveled 70 * 3 = 210 km.
3. During all this time, they together covered 80 + 210 = 290 km.
