A train takes 2 hours longer to go an equal distance of a car. If the car and the train leave station A at the same time, and the car reaches station B 4.5 hours later, calculate the combined time the car and the train take to reach station B.
Let's think: Since the train takes 2 hours longer to go an equal distance as the car, to reach station B, the train took 4.5 + 2 = 6.5 hours. Together, the train and the car take a total of 6.5 + 4.5 = 11 hours to travel from station A to station B.. The answer is: 11.

Jerusha earned 4 times as much money as Lottie. Together they earned $85. How many dollars did Jerusha earn? Use L to represent Lottie's earnings.
Let's think: L = Lottie's earnings. Jerusha's earnings = 4L. L + 4L = 85. L = 85 / 5. L = 17 so Jerusha earned 4L = 4(17) = 68. Jerusha earned $68.. The answer is: 68.

Irene shares half of a small apple with her dog every day. A small apple weighs about 1/4 of a pound. She can currently buy apples for $2.00 a pound. How much will she spend so that she and her dog have enough apples to last for 2 weeks?
Let's think: There are 7 days in a week and she needs apples for 2 weeks so that's 7 * 2 = 14 days. She shares an apple with her dog every day so for 14 days so she needs 1 * 14 = 14 apples. Each apple weighs 1 / 4 of a pound and she needs 14 apples so that's .25 * 14 = 3.5 pounds of apples. She needs 3.5 pounds of apples and they are on sale for $2.00 a pound so she will spend 3.5 * 2 = $7.00 for apples.. The answer is: 7.

At the polar bear club, Jerry and his three friends, Elaine, George, and Kramer, took turns jumping into a swimming pool filled with freezing-cold water. Jerry was in the pool for 3 minutes before becoming too cold to remain in the cold water. Elaine stayed in the pool for twice as long as Jerry. George could only stay in the pool for one-third as long as Elaine. And Kramer, who accidentally locked himself in the bathroom, could not find the pool. What is the combined total of minutes that Jerry and his friends were in the cold water?
Let's think:
Elaine was in the pool for 2 * 3 = 6 minutes. George was in the pool for 6 / 3 = 2 minutes. Kramer never found the pool and thus swam for 0 minutes. In total, Jerry and his friend were in the cold water for 3 + 6 + 2 + 0 = 11 minutes.. The answer is: 11.
