Question 433140: The Martins plan a 3-Week trip with a budget of $600 for renting a car. Car rental rates are $135/week plus $0.17/km. Write a formula to show the number of kilometers the Jacksons can travel.
I have figured out the answer, but I know I should use d=rt; however, I'm not sure where to enter each number I've come up with. Here is what I have:
600 / 3 = 200, budget / # of weeks
200 – 135 = 65, per wk budget – weekly car cost = balance for mileage
65 / 0.17 = 382, per wk budget / cost per km = km per wk
382 * 3 = 1146, km per wk * # of wks = total km can travel
How do I get this in d=rt format? I'm so confused if I should even be using that formula anyhow. Thanks! Debi 4/8/11

Question 433224: Pick two animals to be in a race and answer the following questions.
a. Suppose two animals are in a race. Choose the two animals and calculate the speed of each animal in yards per second. my answers:
Cheetah 70 mph
70 miles x 1 hour x 1760 yds = 34.2 yds/sec
1 hour 3600 sec 1 mile
Fox 42 Mph
42 miles x 1 hour x 1760 yds = 20.5 yds/sec
1 hour 3600 1 mile
b. Decide how much of a head start (in yards) the faster animal offers the slower animal. For each animal, write an equation relating distance from the starting line to time. (This is where I am having trouble.. these are my answers but they just doesn't seem right! I have to graph them and the graph seems weird.)
Fox 348.5y=20.5x
Cheetah y=34.2x
