Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:

Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
and cross multiply to solve:
638x = 4466 so
x = 7 hrs
First you take 29 over 185 and x over 100 and you cross multiply which gives you 185x is equal to 2900 then you take 185x and 2900 and you divide both by 185 and you end up with x equals 15.68 or 15.68% which is letter B
Answer: I think the answer would be -4
