The boat covers the distance between the two marinas in 6 hours, and the distance 72 km less in 4 hours. What is the speed of the boat? How far will he swim in 5 hours.
Determine how many hours the boat travels 72 km:
6 – 4 = 2 hours;
Now you can calculate the speed of the boat, because it covers 72 km in 2 hours. By reducing this ratio, we find the speed:
72/2 = 36 km / h;
The distance that the boat will sail in 5 hours is calculated by multiplying the speed by the time:
5 * 36 = 180 km.
Answer: 1) the speed of the boat is 36 km / h; 2) the boat will cover 180 km in 5 hours.
