Answer
38°
Step-by-step explanation:
52+90+x=180
180-52-90=x
x=38
11 x 0.95 L = 10.45 L so then 20.25 L - 10.45 L = 9.8 L
72 and 96 are divisible by 3, 6, and 8.

Let’s call the speed of the slower car S, then the speed of the other is S+10mph.
At 5pm they have been travelling for 3 hours. The slower car travels a distance 3S and the faster one 3(S+10).
But the two distances must add up to 240 miles so 3S+3(S+10)=240, 3S+3S+30=240, 6S=210, S=35 mph. The faster car’s speed is 45mph. We can see that 3S is the same distance as 3x, so x=S=35 mph, and the distance the faster car travels is 3×45=135 miles.
