Question

На дорогу от поселка до города на грузовой машине требуется 48 л бензина. Хватит ли для поездки в город и обратно 100 л бензина? 90 л бензина?

Answer 1

Значит так. Решаем:
1) 100: 48 = 2 ( ост.4). Хватит на поездку туда и обратно.
2) 90:48=1 ( ост. 42). Хватит только на поездку в город, на обратную не хватит.

Answer 2

Calculating Fuel Required for the Trip

To calculate the fuel required for the trip from the village to the city and back, we can use the following information:

- The trip from the village to the city and back requires 48 liters of fuel. - We want to determine if 100 liters of fuel or 90 liters of fuel will be sufficient for the round trip.

Using the provided information, we can calculate the fuel required for the round trip:

1. 48 liters for one-way trip: The round trip from the village to the city and back requires 48 liters of fuel.

Analysis of Fuel Sufficiency

Now, let's analyze the sufficiency of 100 liters and 90 liters of fuel for the round trip:

- 100 liters of fuel: According to the calculation, 100 liters of fuel is more than the required 48 liters for the round trip. Therefore, 100 liters of fuel will be sufficient for the round trip.

- 90 liters of fuel: Similarly, 90 liters of fuel is less than the required 48 liters for the round trip. Therefore, 90 liters of fuel will not be sufficient for the round trip.

In conclusion, for the round trip from the village to the city and back, 100 liters of fuel will be sufficient, while 90 liters of fuel will not be sufficient.
