Question

Один самосвал перевез 150 т щебня,а другой-такой же грузоподъемности-100 т. сколько рейсов сделал каждый из них,если первый совершил на 2 рейса больше?

Answer 1

1) 150 - 100 = 50 (т) щебня перевезено за указанные 2 рейса
2) 50 : 2 = 25 (т) щебня  перевозятся за 1 рейс
3) 150 : 25 = 6 (рейсов) сделал один самосвал
4) 100 : 25 = 4 (рейса) - другой самосвал
Ответ: 6 рейсов сделал один самосвал, 4 рейса - другой самосвал.

Answer 2

Calculation of the Number of Trips

To calculate the number of trips made by each dump truck, we need to compare their carrying capacities and the difference in the number of trips made by the first truck.

Let's assume that the first dump truck made x trips. Since the second dump truck made 2 trips less than the first one, it made x - 2 trips.

The carrying capacity of the first dump truck is 150 tons, and the carrying capacity of the second dump truck is 100 tons.

To find the total amount of material transported by each dump truck, we can multiply the carrying capacity by the number of trips made.

For the first dump truck: - Carrying capacity: 150 tons - Number of trips: x - Total amount of material transported: 150 tons * x trips = 150x tons

For the second dump truck: - Carrying capacity: 100 tons - Number of trips: x - 2 - Total amount of material transported: 100 tons * (x - 2) trips = 100(x - 2) tons

Now, we can set up an equation to solve for x:

150x = 100(x - 2)

Let's solve this equation to find the value of x.

150x = 100x - 200

50x = 200

x = 4

Therefore, the first dump truck made 4 trips, and the second dump truck made 2 trips.

Please note that the above calculation assumes that the carrying capacity of the dump trucks is fully utilized in each trip and that there are no other constraints or factors affecting the number of trips made.
