Question

Для перевозки груза автомашины грузоподемностью 7,5т пришлось сделать 12рейсов .Сколько рейсов придется сделать автомашине грузо подемностью 9 т для переалзкт этого же груза

Answer 1

7.5*12=90т ей пришлось перевезти
90/9=10 раз ей придется съездить

Answer 2

Calculation of Required Trips for 9-ton Capacity Truck

To calculate the number of trips required for a 9-ton capacity truck to transport the same load that took 12 trips for a 7.5-ton capacity truck, we can use a simple proportion.

Let's denote: - T7.5: Number of trips for a 7.5-ton capacity truck - T9: Number of trips for a 9-ton capacity truck - C: Capacity of the trucks (in tons)

The proportion can be set up as follows: T7.5 / 12 = T9 / X

Where X is the number of trips for the 9-ton capacity truck.

Calculation

Using the proportion, we can solve for T9: T9 = (T7.5 / 12) * X

Given that it took 12 trips for the 7.5-ton capacity truck and we want to find out how many trips are needed for the 9-ton capacity truck, we can proceed with the calculation.

Solution

T9 = (12 / 7.5) * 9

T9 = 12 * (9 / 7.5)

T9 = 12 * 1.2

T9 = 14.4

So, the 9-ton capacity truck would need approximately 14.4 trips to transport the same load that took 12 trips for the 7.5-ton capacity truck.

Conclusion

Therefore, the 9-ton capacity truck would need approximately 14.4 trips to transport the same load that took 12 trips for the 7.5-ton capacity truck. Since it's not possible to make a fraction of a trip, the truck would need to make 15 trips to complete the transportation.
