[Question]An eagle can fly 15 miles per hour; a falcon can fly 46 miles per hour; a pelican can fly 33 miles per hour; a hummingbird can fly 30 miles per hour. If the eagle, the falcon, the pelican, and the hummingbird flew for 2 hours straight, how many miles in total did the birds fly?
[Answer]An eagle can fly 15 x 2 = 30 miles for 2 hours. A falcon can fly 46 x 2 = 92 miles for 2 hours. A pelican can fly 33 x 2 = 66 miles for 2 hours. A hummingbird can fly 30 x 2 = 60 miles for 2 hours. Therefore, the birds flew a total of 30 + 92 + 66 + 60 = 248 miles for 2 hours. The answer is 248.
Q: Mustafa buys a fridge, a TV and a computer with a total budget of $1600. The TV costs $600 and the fridge costs $500 more than the computer. How much does the computer cost?

Question: Josh has $300 in his wallet, and $2000 invested in a business. If the business's stock price rises 30% and then he sells all of his stocks, how much money will he have in his wallet?
Answer: If the business's stock price rises 30%, then his share on the company is worth 30% multiplied by $2000 plus $2000 that he already had. That results in 30% * $2000 + $2000 = $600 + $2000 = $2600. Since he already had $300, with $2600 more he will have $300 + $2600 = $2900. The answer is 2900.
Q: Carlos and Diego are racing around the block. Carlos runs around the entire block in 3 minutes. Diego runs around half the block in 2.5 minutes and then is tripped by a dog and can't finish. Assuming he kept up the same speed the entire race, what would've been the average time in seconds for the racers?
A:
If he finished the race, it would've taken 5 minutes because 2.5 x 2 = 5. Their total time would've been 8 minutes because 3 + 5 = 8. The average would've been 4 minutes because 8 / 2 = 4. The average time in seconds would've been 240 because 4 x 60 = 240. The answer is 240.
