Each taxi travels 7 kilometers more than each car.
Together, the 5 taxis travel +7%2A5+=+35+ mi more than
the 4 cars
--------------
Let +d+ = the distance traveled by the 4 cars
+d+%2B+d+%2B+35+=+125+
+2d+=+90+
+d+=+45+
and
+d+%2B+35+=+80+
------------------
For the 4 cars:
+45%2A%28+1%2F10+%29+=+4.5+ liters
The cars use 4.5 liters of gas in 1 day
-----------------------------------
I'm not sure about the wording of th last sentence.
"How much gas do THE CARS use in a day if THEY use
1 liter of gas for every 10 kilometers traveled?"
All 4 cars together?
Just 1 car?
I solved it for all 4 cars together
