Question

За 6 ч лодка проплыла 66 км.Сколько километров проплыла бы лодка за это же время,если бы её скорость уменьшилась на 4 км/ч?спасибо.

Answer 1

6*(66:6-4)= 42километра

Answer 2

1) 66:6=11(км/ч)-скорость лодки,когда она проплыла 66 км 2)11-4=7(км/ч) 3) 7*6=42(км)

Answer 3

Calculating Distance Traveled

To calculate the distance traveled by the boat at a reduced speed, we can use the formula:

Distance = Speed × Time

Given that the boat initially traveled 66 km in 6 hours at a speed of 11 km/h, we can calculate the distance it would travel at a reduced speed of 7 km/h.

Using the formula, the distance traveled at the reduced speed would be:

Distance = 7 km/h × 6 hours

This simplifies to:

Distance = 42 km

So, the boat would travel 42 kilometers at the reduced speed of 7 km/h in the same 6-hour time period.
