A car from a to B, 60 kilometers per hour, 3 hours of the whole line 2 / 5, the car with the same speed to complete the whole line, also need a few hours
=60*3/2*5 /60 -3
How many liters of gasoline does this car use for one kilometer?
You need formulas and numbers. Well done, you can offer more reward points! Answer it as soon as possible.
3/25÷3/2
=3/25×2/3
=2 / 25 (L)
A: this car uses 2 / 25 liters of gasoline for 1km
A car used to consume 20 / 3km of fuel for 1km, but now the fuel consumption per kilometer is 13 / 15 of the original amount. According to this calculation, how many kg of gasoline is needed for 100km
Is it the original fuel consumption of 3 / 20kg per km? The following answers are based on this
Original fuel consumption of 100km: 100 * 3 / 20 = 15kg
After that, the fuel consumption per kilometer becomes 13 / 15 of the original
The current fuel consumption is 15 * (13 / 15) = 13 kg
A car consumes 1 / 4 of a liter of fuel when it travels 8 / 5 km. How many liters does this car consume when it travels 1 km
1 km fuel consumption; 1 / 4 △ 8 / 5 = 5 / 32 = 0.156 L
