Answer:
9 hours and 20 minutes.
Step-by-step explanation:
In one hour, Amanda can proofread 17 reports.
In one hour, Sally can proofread 28 reports.
That means together, they can proofread 45 reports in one hour.
So we need to divide the total amount of reports by how much they can read in an hour:
420/45 = 28/3 = 9 1/3
The time it takes between the two of them is 9 hours and 20 minutes.
32 miles is the same as 19.8839 kilometers
There are 3.78541 liters in a gallon
Now we divide the two.
19.8839 / 3.78541 ≈ 5.25
The American car gets 5.25 km per liter. So the European car is better on gas economy.
