Jason has to drive home which is 120 miles away. If he drives at 60 miles per hour for 30 minutes, what speed does he have to average for the remainder of the drive to get there in exactly 1 hour 30 minutes?
Let's think: Jason drives 60 miles per hour * 0.5 hours = 30 miles initially. He needs to drive an additional 120 miles total - 30 miles driven = 90 more miles. He has 1.5 hours - 0.5 hours = 1 hour to drive the remaining distance. He must average 90 miles per hour to drive the remaining 90 miles in 1 hour.. The answer is: 90.

Peter and his dad Rupert shared the same birthday. To make it special, they each got their own birthday cake. Peter has 10 candles on his cake. Rupert is 3 and 1/2 times older than Peter. How many candles will be on Rupert's cake?
Let's think: Peter is 10 years old because he has 10 birthday candles on his cake. Rupert is 3.5 times older than Peter so Rupert will have 3.5 * 10 = 35 candles on his cake.. The answer is: 35.

The first tank is 300 liters filled while the second tank is 450 liters filled. The second tank is only 45% filled. If the two tanks have the same capacity, how many more liters of water are needed to fill the two tanks?
Let's think: Since 450 liters represents 45%, then each 1% is equal to 450 liters / 45 = 10 liters. Hence, the capacity of each tank is 10 liters x 100 = 1000 liters. So, the first tank needs 1000 - 300 = 700 liters of water more. While the second tank needs 1000 - 450 = 550 liters more. Therefore, 700 + 550 = 1250 liters of water are needed to fill the two tanks.. The answer is: 1250.

The Period 1 gym class has 5 fewer than twice as many students as in the Period 2 gym class. There are 11 students in the Period 1 gym class. How many are in the Period 2 gym class?
Let's think:
Let x be the number of students in the Period 8 gym class. 2x - 5 = 11. 2x = 16. x = 8.. The answer is: 8.
