Question

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

Answer 1

1.240:3=80 км/ч - скорость катера на подводных крыльях 2.80:4=20 км/ч - скорость обычного катера 3.80:20=4 раза скорость катера на крылья больше чем простого катера

Answer 2

Calculation of Speed

To determine the ratio of the speed of the submarine-winged boat to the regular boat, we need to calculate their respective speeds.

The submarine-winged boat traveled a distance of 240 km in 3 hours, while the regular boat traveled a distance of 80 km in 4 hours.

To calculate the speed of each boat, we can use the formula:

Speed = Distance / Time

For the submarine-winged boat: Speed = 240 km / 3 hours = 80 km/h

For the regular boat: Speed = 80 km / 4 hours = 20 km/h

Ratio of Speeds

To find the ratio of the speed of the submarine-winged boat to the regular boat, we divide the speed of the submarine-winged boat by the speed of the regular boat:

Ratio = Speed of Submarine-winged Boat / Speed of Regular Boat

Ratio = 80 km/h / 20 km/h = 4

Therefore, the speed of the submarine-winged boat is 4 times greater than the speed of the regular boat.
