What grade are you learning this in
The answer is -4 and 21
I am glad to help!
4 times 2 is 8 and 8-4 is 4 so 4 X10 is 40 plus 8 is 48
4768 x 1551 is 7395168
7395168 divided by 10.2 is 725016.5 (rounded to the nearest tenths)
<span>In order to meaningfully compare the distance per unit of fuel, we need to convert one set of measurements into the same units as the other set of measurements. Doesn't matter if we convert miles per gallon to kilometers per liter or visa versa. So let's convert 32 miles per gallon to kilometers per liter.
32 mile/gal * 1.60934 km/mile / 3.78541 L/gal = 13.60457124 km/L
And since 13.6 km/L is better than 12.7 km/L, the American car gets better gas mileage than the European car.
To demonstrate that it didn't matter which we converted, let's do the problem again, except this time we'll convert from km/L to miles/gal. So
12.7 km/L / 1.60934 km/mile * 3.78541 L/gal = 29.87231225 mile/gal
And once again, 32 mile/gal is higher than 29.9 mile/gal. So the American car still has better gas mileage.</span>
