Question

Один велосипедист проехал 24 км,двигаясь со средней скоростью 200 м/мин,а другой это же расстояние проехал со скоростью 12км/ч.Сколько времени потратил каждый из велосипедистов?

Answer 1

24км=24000
1)24000:200=120(м)-потратил 1-ый.
2)120:60=2(ч)-первый
3)24:12=2(ч)-второй
Ответ :первый проехал 2 часа,второй проехал 2 часа

Answer 2

Calculation of Time Taken by Each Cyclist

To calculate the time taken by each cyclist, we need to use the formula:

Time = Distance / Speed

Let's calculate the time taken by each cyclist:

1. Cyclist 1: - Distance: 24 km - Speed: 200 m/min

To calculate the time taken by Cyclist 1, we need to convert the speed from meters per minute to kilometers per hour. There are 60 minutes in an hour, so we can multiply the speed by 60 to convert it to meters per hour. Then, we divide by 1000 to convert it to kilometers per hour.

Speed of Cyclist 1: 200 m/min * 60 min/hour / 1000 = 12 km/h

Now we can calculate the time taken by Cyclist 1:

Time taken by Cyclist 1 = Distance / Speed = 24 km / 12 km/h = 2 hours

2. Cyclist 2: - Distance: 24 km - Speed: 12 km/h

The speed of Cyclist 2 is already in kilometers per hour, so we can directly calculate the time taken:

Time taken by Cyclist 2 = Distance / Speed = 24 km / 12 km/h = 2 hours

Therefore, both cyclists took 2 hours to cover the distance of 24 km.
