Question

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

Answer 1

240:3=80
80:4=20
80:20=4

Answer 2

240/3 ÷ 80/4=80/20=4
В 4 раза больше

Answer 3

Calculating the Speed Ratio

To find out how many times faster the speed of the hydrofoil boat is compared to the regular boat, we can calculate their respective speeds and then determine the ratio between them.

The hydrofoil boat covered a distance of 240 km in 3 hours, while the regular boat covered 80 km in 4 hours.

Calculating the Speed of Each Boat

Let's calculate the speed of each boat using the formula: speed = distance / time.

For the hydrofoil boat: - Speed = 240 km / 3 hours = 80 km/h For the regular boat: - Speed = 80 km / 4 hours = 20 km/h

Determining the Speed Ratio

Now, let's determine the ratio of the speed of the hydrofoil boat to the speed of the regular boat.

Speed Ratio = (Speed of Hydrofoil Boat) / (Speed of Regular Boat) = 80 km/h / 20 km/h = 4.

Conclusion

The speed of the hydrofoil boat is 4 times faster than the speed of the regular boat.
