Two motor ships simultaneously set off from two piers towards each other. The distance between the marinas is 315 km.
Two motor ships simultaneously set off from two piers towards each other. The distance between the marinas is 315 km. The speed of the first motor ship is 35 km / h, and the speed of the second is 7 km / h less. 1) What is the distance between the ships in 2 hours? 2) How many hours after departure will the ships meet?
The solution of the problem:
1. To solve the problem, let us find the speed of the second motor ship.
35-7 = 28 kilometers per hour
2. Find how many kilometers the first motor ship will pass in two hours.
35 * 2 = 70 kilometers
3. Determine the distance traveled for 2 hours by the second motor ship.
28 * 2 = 56 kilometers
4. Let’s calculate the distance between the ships in 2 hours.
315- (70 + 56) = 189 kilometers
5. Let’s find the speed of convergence in one hour of two motor ships.
25 + 35 = 63 kilometers
6. Find how many hours after leaving the ships will meet.
315 * 63 = 5 hours
Answer: The distance between the ships will be one hundred and eighty-nine kilometers in two hours, and they will meet each other in five hours.
