Question

Два велосипедиста выехали одновременно навстречу друг другу. скорость одного из них 28 км/ч, скорость второго 33 км\ч. какое расстояние будет между ними за 2 часа до встречи и через 1 час после встречи. расстояние 183 км. срочно!

Answer 1

28+33=61 км/ч скорость сближения
183÷61=3ч через это время встретятся
3-2=1ч
183-1×61=122 км за 2часа до встречи
3+1=4ч
4×61-183=61 км через 1ч после встречи

Answer 2

Calculation of the Distance between the Cyclists

To calculate the distance between the two cyclists, we can use the formula:

Distance = Speed x Time

Let's calculate the distance between the cyclists for the given scenarios.

1. Distance 2 hours before the meeting: - The first cyclist's speed is 28 km/h. - The second cyclist's speed is 33 km/h. - The time before the meeting is 2 hours.

Using the formula, we can calculate the distance:

Distance = Speed x Time

For the first cyclist: Distance1 = 28 km/h x 2 hours = 56 km

For the second cyclist: Distance2 = 33 km/h x 2 hours = 66 km

Therefore, the distance between the two cyclists 2 hours before the meeting is 56 km + 66 km = 122 km.

2. Distance 1 hour after the meeting: - The first cyclist's speed is 28 km/h. - The second cyclist's speed is 33 km/h. - The time after the meeting is 1 hour.

Using the formula, we can calculate the distance:

Distance = Speed x Time

For the first cyclist: Distance1 = 28 km/h x 1 hour = 28 km

For the second cyclist: Distance2 = 33 km/h x 1 hour = 33 km

Therefore, the distance between the two cyclists 1 hour after the meeting is 28 km + 33 km = 61 km.

So, the distance between the two cyclists 2 hours before the meeting is 122 km, and 1 hour after the meeting is 61 km.
