Question

Учащиемя 3 класса решили пройти за день 25км.Первые 2 часа они шли со скоростью 5км/ч.Какое расстояние им осталось пройти?За какое время они пройдут оставшийся путь,двигаясь с той же скоростью?

Answer 1

25 : 5 = 5 км они прошли за 2 часа
25-5= 20 км осталось пройти
4× 2 = 8 за часов

Answer 2

Calculation of Remaining Distance:

To calculate the remaining distance, we need to subtract the distance covered in the first 2 hours from the total distance of 25 km.

The distance covered in the first 2 hours can be calculated by multiplying the speed of 5 km/h by the time of 2 hours:

Distance covered in the first 2 hours = Speed × Time = 5 km/h × 2 hours = 10 km.

Now, we can calculate the remaining distance by subtracting the distance covered in the first 2 hours from the total distance:

Remaining distance = Total distance - Distance covered in the first 2 hours = 25 km - 10 km = 15 km.

Therefore, the students have 15 km left to travel.

Calculation of Time to Cover the Remaining Distance:

To calculate the time it will take for the students to cover the remaining distance of 15 km, we can use the formula:

Time = Distance / Speed.

Since the speed remains the same at 5 km/h, we can substitute the values into the formula:

Time = 15 km / 5 km/h = 3 hours.

Therefore, it will take the students 3 hours to cover the remaining distance of 15 km, moving at the same speed of 5 km/h.
