Sorry could not type exponents
378% is the correct answer. Divide 280 by 100 to find 1 percent. Then multiply by 135 to find 135%
The second one is the best answer in my opinion i'm not sure.
It would be:
-.72 < -5/8 < -.6 < -7/12
(a+a+6)*2.5=345
2a+6=138
a=132/2
a=66 mph
a+6=66+6=72 mph
Speed of the first car is 72 mph
