Question

велосепидист проехал за 2 часа 30 км.за сколько часов,двигаясь так же,он преодолеет расстояние в 90 км?

Answer 1

1)30:2=15(км/ч)-скорость велосипедиста

2)90:15=6(ч)-время велосипедиста

 

Ответ: За 6 часов велосипедист проедет 90 км

Answer 2

Скорость велосипедиста равна: 30/2=15 км/ч

Отсюда находим время: 90/15=6 ч

 

Answer 3

Calculating Time to Cover Distance

To calculate the time it takes for the cyclist to cover a distance of 90 km at the same speed, we can use the formula: time = distance / speed.

Given that the cyclist covered 30 km in 2 hours, we can calculate the speed: - Speed = Distance / Time = 30 km / 2 hours = 15 km/h.

Now, we can use the calculated speed to find the time it takes to cover 90 km: - Time = Distance / Speed = 90 km / 15 km/h = 6 hours.

So, the cyclist will take 6 hours to cover a distance of 90 km at the same speed.
