Question

За 3 часа катер на подводных крыльях проплыл 240 км. Идущий вслед за ним обычный катер проплыл 80 км за 4ч. Во сколько раз скорость катера на подводных крыльях больше?

Answer 1

В 4 раза скорость катера на подводных крыльях больше

Answer 2

Calculation of Speed

To determine the ratio of the speed of the catamaran on underwater wings to the speed of the regular boat, we need to calculate the speeds of both vessels.

The catamaran on underwater wings traveled a distance of 240 km in 3 hours. Therefore, its speed can be calculated by dividing the distance by the time:

Speed of the catamaran on underwater wings = Distance / Time = 240 km / 3 hours = 80 km/h.

The regular boat traveled a distance of 80 km in 4 hours. Therefore, its speed can be calculated by dividing the distance by the time:

Speed of the regular boat = Distance / Time = 80 km / 4 hours = 20 km/h.

Ratio of Speeds

To find the ratio of the speed of the catamaran on underwater wings to the speed of the regular boat, we divide the speed of the catamaran by the speed of the regular boat:

Ratio of speeds = Speed of the catamaran on underwater wings / Speed of the regular boat = 80 km/h / 20 km/h = 4.

Therefore, the speed of the catamaran on underwater wings is 4 times greater than the speed of the regular boat.
