Question

Корабль проплыл 300 км за 3 часа.сколько времени он потратит,чтобв проплыть 600 км,если скорость увеличить на 50 км/ч?

Answer 1

1)300:3=100(км/ч)- скорость
2)100+50=150(км/ч)-новая скорость
3)600:150=4(ч)-понадобится
Ответ:4 часа.

Answer 2

1)300:3=100(км/ч) - старая скорость катера
2)100+50=150(км/ч) - новая скорость катера
3)600:150=4(ч) - время, чтобы проплыть 600 км
Ответ: 4 часа

Answer 3

Calculating Time to Travel 600 km with Increased Speed

To calculate the time it will take for the ship to travel 600 km at an increased speed, we can use the formula:

Time = Distance / Speed

Given: - Initial distance traveled = 300 km - Initial time taken = 3 hours - Increased speed = 50 km/h

We can calculate the initial speed using the initial distance and time: Initial Speed = Initial Distance / Initial Time

Then, we can calculate the new time using the increased speed and the total distance: New Time = Total Distance / Increased Speed

Let's calculate the time it will take for the ship to travel 600 km with the increased speed.

Calculation

1. Initial Speed: - Initial Distance = 300 km - Initial Time = 3 hours

Initial Speed = 300 km / 3 hours = 100 km/h

2. New Time with Increased Speed: - Total Distance = 600 km - Increased Speed = 100 km/h + 50 km/h = 150 km/h

New Time = 600 km / 150 km/h

Result

The ship will take 4 hours to travel 600 km with the increased speed of 150 km/h.
