Question

Два вилосипеда выехали одновременно из одного пункта в одном направлении. Скорость одного велосипета 17 2\3 км\ч, скорость другого - 15 2\5 км\ч. какое расстояние будет между ними через 3 ч.

Answer 1

1)17 2/3*3=53/3*3=53 (км) проедет первый велосипедист за 3 часа
2)15 2/5*3=77/5*3=231/5=46 1/5 (км) проедет второй велосипедист за 3 часа
3)53-46 1/5=52 5/5-46 1/5=6 4/5 (км) - будет между велосипедистами через 3 часа

Answer 2

Calculation of Distance between Two Bicycles

To calculate the distance between two bicycles that start simultaneously from the same point and travel in the same direction, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the two bicycles after 3 hours.

The speed of one bicycle is 17 2/3 km/h, and the speed of the other bicycle is 15 2/5 km/h.

Using the formula, we can calculate the distance for each bicycle:

For the first bicycle: Distance1 = Speed1 × Time = (17 2/3) km/h × 3 h

For the second bicycle: Distance2 = Speed2 × Time = (15 2/5) km/h × 3 h

To calculate the distances, we need to convert the mixed fractions into improper fractions:

17 2/3 = (3 × 17 + 2)/3 = 53/3 15 2/5 = (5 × 15 + 2)/5 = 77/5

Now we can calculate the distances:

For the first bicycle: Distance1 = (53/3) km/h × 3 h = 53 km

For the second bicycle: Distance2 = (77/5) km/h × 3 h = 46.2 km

Therefore, the distance between the two bicycles after 3 hours is approximately 53 km.
