Question

Один трактор перевозит 168 бревен за 14 рейсов а другой 152 бревна за 19 рейсов За сколько рисового трактора могут перевезти 340 брёвен работы вместе

Answer 1

....................................

Answer 2

1-трактор-168брев.14рейс.
2-трактор-152брев.19рейс.
168:14=12
152:19=8
12+8=20
340:20=17
Правильный ответ 17

Answer 3

Calculation of the Number of Trips for Each Tractor

To find out how many trips the rice tractors can make together to transport 340 logs, we need to calculate the number of trips each tractor can make individually.

The first tractor can transport 168 logs in 14 trips, which means it can transport 168/14 = 12 logs per trip.

The second tractor can transport 152 logs in 19 trips, which means it can transport 152/19 = 8 logs per trip.

Calculation of the Total Number of Trips

To calculate the total number of trips required to transport 340 logs, we need to divide the total number of logs by the number of logs each tractor can transport per trip.

Let's calculate the number of trips for each tractor:

- The first tractor can transport 12 logs per trip, so it would require 340/12 = 28.33 trips (rounded up to the nearest whole number, which is 29 trips). - The second tractor can transport 8 logs per trip, so it would require 340/8 = 42.5 trips (rounded up to the nearest whole number, which is 43 trips).

Calculation of the Total Number of Trips Together

To find out how many trips the rice tractors can make together, we need to add the number of trips for each tractor:

- The first tractor requires 29 trips. - The second tractor requires 43 trips.

Therefore, the rice tractors can make a total of 29 + 43 = 72 trips together to transport 340 logs.

Please note that the above calculations are based on the given information and assumptions.
