Question

Велосипедист каждый день ездит 3 часа по дороге ,длина которой 15 км. сколько он сделал полных кругов за 7 дней, если каждый день онигачинает круг сначала и его скорость равна 22 км/ч

Answer 1

22*3=66км
66*8=528км
528:12=44км
Ответ 44

Answer 2

Calculating the Number of Full Circuits

To calculate the number of full circuits the cyclist completes in 7 days, we can use the information provided about the cyclist's daily routine and speed.

The cyclist rides for 3 hours each day at a speed of 22 km/h, covering a road that is 15 km long.

First, let's calculate the distance the cyclist covers in 3 hours at a speed of 22 km/h:

Distance covered in 3 hours: - Distance = Speed × Time - Distance = 22 km/h × 3 h - Distance = 66 km

Now, we need to find out how many full circuits the cyclist completes in 7 days. To do this, we'll calculate the number of circuits completed in one day and then multiply it by 7.

Number of circuits completed in one day: - Circuits completed in one day = Distance covered in 3 hours / Length of the road - Circuits completed in one day = 66 km / 15 km - Circuits completed in one day ≈ 4.4

Since the cyclist starts each circuit from the beginning, we can consider the number of full circuits completed in 7 days to be the integer part of the result, which is 4 circuits per day.

Number of full circuits completed in 7 days: - Circuits completed in 7 days = Circuits completed in one day × 7 - Circuits completed in 7 days = 4 circuits/day × 7 - Circuits completed in 7 days = 28 circuits

So, the cyclist completes 28 full circuits in 7 days.
