Question

Снегоуборочная машина число 60 километров дороги за 10 часов а вторая за 15 часов За сколько времени они смогут очистить этот участок дороги работая вместе с той же производительностью

Answer 1

1)60:10=6(км)- дороги чистила первая машина за 1 час
2)60:15=4(км)- дороги чистила вторя машина за 1 час
3)6+4=10(км)-дороги смогут очистить за час обе машины
4)60:10=6(ч)-две машины смогут очистить этот участок дороги, работая вместе.

Answer 2

60×10=600
600:16=40
Ответ : 40

Answer 3

Calculation of Time Required to Clear the Road

To determine the time required to clear the given stretch of road, we need to calculate the combined productivity of the two snow removal machines.

Let's assume that the first snow removal machine clears 60 kilometers of road in 10 hours, and the second machine clears the same distance in 15 hours.

To find the combined productivity, we can calculate the reciprocal of the time taken by each machine to clear the road. Then, we add these reciprocals together and take the reciprocal of the sum.

The formula for combining the productivity of two machines is as follows:

Combined Productivity = 1 / (1/Time Machine 1 + 1/Time Machine 2)

Let's calculate the combined productivity:

Time Machine 1 = 10 hours

Time Machine 2 = 15 hours

Combined Productivity = 1 / (1/10 + 1/15)

Using this formula, we find that the combined productivity is 6 hours.

Therefore, working together at the same productivity, the two machines will be able to clear the given stretch of road in 6 hours.

Please note that the above calculation assumes that the productivity of the machines remains constant throughout the entire duration of the task.
