Question 508764: I wrote this question earlier but I forgot to show what I tried but am not sure if it's right
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Exactly 30 minutes after the Andersons' head south on the highway, the Quentins' set out from the same point and follow the same route. The Andersons' travel at 50 mi/h. The Quentins' travel at 65 mi/h. How long does it take the Quentins' to overtake the Andersons'?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~Chart(This is what I did & I converted 30 minutes to 1/2)
_____________|Rate x Time = Distance |
Andersons____| 50 x t = 50t |
Quentins_____| 65 x t-1/2 = 65(t-1/2)|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~Equation(When I solved it I felt the answer didn't make sense please tell me if I got this right or wrong)
50t= 65(t-1/2)
50t= 65t-65/2
-65t=-65t-65/2
-15t=-65/2
t= 2.1666666 repeats
please tell me what I did wrong or if I got it right and tell me the right equation and answer so I can try and work out the problem. Thank you and please get back to me before 8:00 today 10/3/2011

Question 508371: Richard had to arrive at the airport at exactly 10 am. If he is able to drive at an average speed of 60 miles per hour he would arrive early at 9 am. If he drives at an average speed of 40 miles per hour he would arrive late at 11am. How fast should he travel to arrive at the airport at 10 am exactly?
You need to assume that Richard sets out at the same time in each scenario. You are not told what this time is and are not asked for it, but could work it out from the information given. You are asked to work out what his average speed should be if, after setting out at the same time as in the first two examples, he is to arrive exactly on time.

Question 509063: During the trip, Brent had visibility problems due to the fog. After 1 1/2 hours of fog cleared he was able to increase his speed by 34 mph, driving another 41/2 hours. If the entire trip was 297 miles, how fast was he traveling in the fog?
Tried to figure it out by turning the fractions to decimals, I think that there are just to many steps and I was unsure of how to start what. I know the formula rt=d, but that didnt help much.
Thank you!
