Two boats sail along the same route in the same direction. The speed of the boat sailing in front is 26 km / h

Two boats sail along the same route in the same direction. The speed of the boat sailing in front is 26 km / h, and the speed of the boat sailing behind is 34 km / h. Now there are 40 km between them. How far apart will they be in 2 hours? How long will it take for the second boat to catch up with the first? 1) What is the speed of convergence of boats? 2) How many kilometers will the distance between boats decrease in 2 hours? 3) What will be the distance between them in 2 hours? 4) How many hours will the second boat catch up with the first?

v1 = 24 km / h – speed of the first boat;
v2 = 34 km / h – speed of the second boat;
S = 40 km – initial distance between boats;
t = 2 hours;
t1 =? S2 =?

Let’s find the speed of convergence of two boats:
v sb = v2 – v1 = 34 – 24 = 10 km.

Let’s determine how many kilometers the distance between them will decrease in 2 hours:
S1 = 10 * 2 = 20 km.

Let’s calculate the distance that remains between the boats:
S2 = S – S1 = 40 – 20 = 20 km.

Let’s find how long it takes for the second boat to catch up with the first:
t1 = S / v sb = 40/10 = 4 h.
