Question

Вася ехал на велосипеде и проезжал каждую минуту 500м. Так он ехал 20 м. Затем после случайного прокола колеса оставшийся путь он шёл пешком, проходя 50 м за минуту. Сколько времени он шёл с велосипедом, если общий путь составил 12 км?

Answer 1

За 20 мин.Вася проехал на велосипеде 500*20=10 000 м.= 10 кмЗначит пешком он прошел 12-10=2 км = 2000 м, за время2000:50= 40 мин.
Ответ: пешком Вася шел 40 минут.

Answer 2

Calculation of Time Spent Walking and Cycling

To calculate the time spent walking and cycling, we need to determine the distances covered in each mode of transportation.

Vasya cycled for 20 meters before experiencing a flat tire. After that, he walked the remaining distance. The total distance covered was 12 kilometers, which is equivalent to 12,000 meters.

Let's calculate the time spent walking and cycling:

1. Distance cycled: 20 meters 2. Distance walked: 12,000 meters - 20 meters = 11,980 meters

Vasya cycled at a speed of 500 meters per minute, and he walked at a speed of 50 meters per minute.

To calculate the time spent cycling, we divide the distance cycled by the cycling speed:

Time spent cycling = Distance cycled / Cycling speed = 20 meters / 500 meters per minute = 0.04 minutes

To calculate the time spent walking, we divide the distance walked by the walking speed:

Time spent walking = Distance walked / Walking speed = 11,980 meters / 50 meters per minute = 239.6 minutes

Therefore, Vasya spent approximately 0.04 minutes cycling and 239.6 minutes walking.

Please note that the calculated time spent walking and cycling may not be exact due to rounding errors.
