If Keith had 1 1/2 cups, he can't use <span>5 2/3 cups. He cant use more than what he had. There is error in this question.</span>
<span>(110 - 96)/110 * 100 = 12.73%
Hope that helps!</span>
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
It is 55% because just multiply it by 100.
Recall d = rt, distance = rate * time.
now, he has a speed rate of 56 mph for a distance of 504

so, at that speed the whole driving time is 9 hours then. Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.
how many miles is it for 7 hours at 56mph? d = rt ---> d = 56 * 7
that many miles he drove yesterday.
