Q: Amanda's car takes five fewer minutes to complete the same trip to the beach than the bus. If the bus takes 40 minutes to drive 80 miles to the beach, how many minutes will it take the car to make a round trip?
A: If the bus takes 40 minutes to complete 80 miles of a trip, Amanda's car, which takes five fewer minutes to complete a trip than the bus, will take 40 - 5 = 35 minutes to complete the trip. A round trip will take the car twice the time for going one way, a total of 35 + 35 = 70. The answer is 70.

Q: Each month, Diego deposits his $5,000 paycheck into a bank account, which he then uses for all of his expenses, which amount to $4,600 per month. How much, in dollars, does Diego save over the course of a year?

Q: A dog barks 30 times per minute. If 2 dogs bark 30 times per minute, how many times will they have barked after 10 minutes?
A:
There are 2 dogs and they each bark 30 times per minute so together they bark 2 * 30 = 60 times per minute. 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60 * 10 = 600 times. The answer is 600.
