1) the car has travelled 210 miles in 3.5 hours
2) No because the line stops at (1,50)
Answer:
Refer to explanation^
Step-by-step explanation:
As stated in the solution, 3/7 is a negative fraction.
To make it less confusing,
2/7 x (-3/7)
Multiply the numerator with the other numerator and the denominator multiply with the other. Like...
2 multiply 3 = 6 (numerator)
7 multiply 7 = 49 (denominator)
Since the 2nd fraction is a negative, the answer is negative too.
If you convert the fraction to a decimal, it gives -0.1224489796
I got 54.90196 for that problem
Car A: 18/20(60)=54 mph
Car B: 13/12(60) = 65 mph
So car b travels 11 more miles than car a in one hour
