A truck at a speed of 43 km / h and a passenger car at a speed of 56 km / h drove out of the two cities at the same time towards each other. In how many hours will they meet if the distance between cities is 693 km?
1) 43 + 56 = 99 (km / h) speed of convergence of a truck and a car with each other.
If you know the distance that the cars have traveled and the speed from the approach, you can find the time after which they will meet using the formula:
t = S: v, notation: t – time, S – distance, v – speed.
The cars, in total, drove 693 km, and the speed of their convergence was 99 km / h.
Let’s find the time after which they met:
2) 693: 99 = 7 (h) time after which the cars will meet.
Answer: 7 hours.
