Question

Мальчик живет в 3х км от парка .Сможет ли он дойти до парка за 40минут со скоростью 4км/час

Answer 1

1)  40 мин = 40/60 = 2/3 часа

2) 3 :4 = 3/4часа - потребуется дойти от дома со  скоростью 4 км/час

3) Сравниваем  2/3  и 3/4, приводя к общему знаменателю, имеем 9/12 и 8/12, т.е.нужно 9/12, а проходит за 8/12, значит успеет.

Answer 2

Calculating Time to Reach the Park

To determine if the boy can reach the park in 40 minutes while walking at a speed of 4 km/h, we can use the formula:

time = distance / speed

Given: - Distance to the park = 3 km - Walking speed = 4 km/h - Time available = 40 minutes

Let's calculate if the boy can reach the park in 40 minutes at this speed.

Calculation

Using the formula time = distance / speed, we can calculate the time it would take for the boy to reach the park:

time = 3 km / 4 km/h

This gives us: time = 0.75 hours

Conclusion

The boy would take 0.75 hours to reach the park at a speed of 4 km/h, which is equivalent to 45 minutes. Since the time available is 40 minutes, the boy would not be able to reach the park within the given time.

Therefore, the boy would not be able to reach the park in 40 minutes while walking at a speed of 4 km/h.

I hope this helps! If you have any other questions, feel free to ask.
