Очень срочно. Завтра сдавать. Расстояние 4 км от дома до реки Вася преодолел на велосипеде за 20 минут. С какой средней скоростью двигался Вася? 1. 0,2км/ч 2. 200м/с 3. 12км/ч 4. 12м/с

Answer 1

2 км/ч 20 минут в 3 раза меньше часа а 4*3=12

Answer 2

12 км/ч 20 минут в 3 раза меньше часа а 4*3=12

Answer 3

Calculation of Vasya's Average Speed

To calculate Vasya's average speed, we need to use the formula:

Average Speed = Total Distance / Total Time

Given that the distance from Vasya's home to the river is 4 km and he covered this distance in 20 minutes, we can proceed with the calculation.

Converting the time from minutes to hours:

Total Time = 20 minutes = 20/60 hours = 1/3 hours

Now, we can calculate the average speed:

Average Speed = 4 km / (1/3 hours) = 12 km/h

Therefore, Vasya's average speed was 12 km/h.

Please note that the answer options you provided do not match the calculated average speed.
