Joe wants to rent a car for a vacation and to pay at most 250 The car rental costs 150 plus 0.25 per mile How far can Joe travel?

400 miles But Joe has forgotten about the cost of gas and his credit card has expired and his girlfriend is just about to leave him...


Joe runs 3 miles in 28 minutes. At the same rate how many miles would he run in 42 minutes?

Well, if Joe runs 3 miles in 28 minutes, that means he's running at a pace of about 0.107 miles per minute. So, if he runs for 42 minutes at the same pace, he would cover approximately 4.5 miles. Math doesn't lie, honey!


Bill can wash a car in 6 minutes Joe can wash the same car in 8 minutes How much time would it take for them to wash that same car working together?

In 1 minute bill washes 1/6 of a car and Joe washes 1/8 of a car. 1/6 + 1/8 = 14/48. A whole care = 48/48. Therefore you should divide 48 by 14 to get 3.429. However since this is in minutes you need to find how much seconds 0.429 of 1 minute is. 0.429 x 60 = 26 seconds (rounded). Add that to the original three minutes and you have 3 minutes 26 sec to wash the entire car working together.

Jill is 16.5 kilometers away from Joe. Both begin to walk toward each other at the same time. Jill walks 3 kilometers per hour If they meet in 3 hours how fast is Joe walking?

Call Joe's speed in kilometers per hour j and the distance Jill has travelled when they meet d. From the physical law that distance d travelled at constant speed equals the product of speed and time t and the problem statement, d = 3 X 3 and the distance travelled by Joe must be 16.5 - d = 7.5. The time walked by each is the same when they meet, since they started at the same time. Joe's speed is the distance he walked divided by the stated time of 3 hours, or 7.5/3 = 2.5 kilometers per hour.
