Question 638920: Please help me solve this word problem. When Chiko 'volunteers' for the army, he says that the ride on the bus lasted 'endless' hours. If the truck he was in was moving at a rate of 30 km/hr and the bus ride lasted for 13 hours, how far did the soldiers take him from home? How far in miles?
I think I divide 13 into 30 which equals 0.43333 but that doesn't make sense..
please e-mail me back at twogunsdown@ymail.com... thank you.

Question 639611: Some bank robbers leave town, speeding at 71 mph. Nine minutes later, the police give chase, traveling at 80 mph. How long will it take after the robbery for the police to overtake the robbers? (Round your answer to three decimal places.)
I have tried over and over to get this right. This is what I have tried:
I made a chart for the robbers saying their rate is 71 mph and time is t+.15 (9 minute head start). Then I made one for cops saying their rate is 80 mph and their time is t. Therefore, the distance of robbers are 71(t+.15) and the distance of cops are 80t. Then I made the equation look like this:
80t = 71(t+.15)
80t = 71t + 10.65 (distribution)
9t = 10.65
t = 1.183
Please help. What am I doing wrong? :(

Question 640291: Wendy took a trip from Davenport to Omaha, a distance of 300mi. She traveled part of the way by bus, which arrived at the train station just in time for Wendy to complete her journey by train. The bus averaged 40mi/h and the train 60mi/h. The entire trip took 5-1/2 hours. How long did Wendy spend on the train?
speed formula is:
speed=distance/time (s=d/t)
However, we are trying to find the time factor so it would be
time=distance/speed (t=d/s)
This is what I THINK the formula is, however I am just stuck at what to plug in to what variable.
I am not good at determining these things when it comes to word problems. Please help. Would be
greatly appreciated.
