Question 57268: ok i worked this problem and got the right answer but only by guessing. I want to know how to set it up so that i can apply it to other problems. Heres the problem: The Jones family drove to Disneyland at 50 mph and returned on the same route at 40 mph. Find the distance to Disneyland if the total driving time was 7.2 hours.
I took the formula D=rt and put distance as unknown so the distance to disneyland is equal to 50mph times 3.2 hours(my guess because it would have taken them less time to travel faster) and distance from disneyland is equal to 40mph times 4 hours(guess) [(3.2+4=7.2)hours] Therefore 50x3.2=160 and 40x4=160 I know from logic that the distance in miles from disneyland and to disneyland has to be equal so the answer to the problem has to be 160. But I dont want to guess, so can you help me set up an equation that will get me the same solution??????

Question 57256: Please help! I think this may be missing something, not sure though.
Boat is traveling from A to B at 33mph
Plane is also traveling from same A to B at 605mph.
Plane takes 104 hours LESS to make the trip.
How far apart are A and B.
It does not say if they left at the same time, but have to assume they did.
It does not say for how long either were traveling.
Thanks in advance!

Question 58613: Hope someone can help quick - I have a test on Monday and am having terrible difficulty with the story probs.
Here's one problem: "Plane took 1 hr. LONGER to fly 480 AGAINST the wind than it took to fly the same distance WITH the wind. If wind speed is 20 mph, what is the speed of plane in calm air?" I don't know how to figure speed of plane just based on air speed. All I know is distance is 480 both ways and time taken is "x + 1" for against wind and "x" for with wind. Can you help?
