Two cars drove out at the same time towards each other from behind two villages, the distance between which is 420 km, and met after 3 hours. The speed of the first car is 61 km / h. How fast was the second car going?
1. We calculate the distance traveled by a car, the speed of which is known, to the meeting point with another car:
61 x 3 = 183 kilometers.
2. We calculate the length of the path covered by the oncoming vehicle in 3 hours:
420 – 183 = 237 kilometers.
3. We calculate with what speed this car was moving:
237: 3 = 79 km / h.
Answer: the second car was moving at a speed of 79 km / h.
