Answer:
the train travels faster than the car
Step-by-step explanation:
first solve for the train multiply 130 by 2 to have it for 4 hours and that would be the car travels 260 miles in 4 hours then divide 130 by 2 to get to five hours which will be the car travels 325 miles in 5 hours so therefore the answer would be the trains travels faster hope this helped :-)
You gotta combine like terms which would be 9x and 12x which gives you 21x .
A. 
To find greater than or smaller than relation, we multiply the terms like (numerator of L.H.S with denominator of R.H.S and put the value on the left side. Then multiply the denominator of L.H.S with numerator of R.H.S and put the value on right side. Now compare the digits.)
So, solving A, we get 810<209 ... This is false
B. 
= 238>589 ..... This is false
C. 
= 496>780 .... This is false
D. 
= 420<660 ..... This is true
Hence, option D is true.
