Question: A school bus traveled for 42 minutes at a speed of 50 mph. What is the distance the bus traveled in miles?
Answer: Step-by-step reasoning process: 1 hour = 60 minutes. We convert the time to hours, so 42 minutes = 42 / 60 hours = 7 / 10 hours. So in 42 minutes, the distance the bus traveled in miles is 50 * (7 / 10) = 35 miles.
So the answer is 35.

Question: Martha has 19 butterflies in her collection. She has twice as many blue butterflies as yellow butterflies. The rest of her butterflies are black. If Martha has 6 blue butterflies, how many black butterflies does she have?
Answer: Step-by-step reasoning process: Martha has 6 / 2 = 3 yellow butterflies. Martha has 6 + 3 = 9 blue and yellow butterflies. Martha has 19 - 9 = 10 black butterflies.
So the answer is 10.

Question: John is working as an IT specialist. He repairs broken computers. One day he had to fix 20 computers. 20% of them were unfixable, and 40% of them needed to wait a few days for spare parts to come. The rest John was able to fix right away. How many computers John was able to fix right away?
Answer: Step-by-step reasoning process: From all the computers, 100% - 40% - 20% = 40% got fixed right away. So John was able to fix 40 / 100 * 20 = 8 computers.
So the answer is 8.

Question: Hayden works for a limousine company as a driver. He gets reimbursed for any gas he puts in the limo, his hourly wage is $15, and he gets paid an additional $5 for every ride he gives. A positive review from a rider in his limo also gets him a $20 bonus. Today, he gave rides to three groups, drove for eight hours, and had to put 17 gallons of gas at $3 per gallon in the limo to refill the tank. He got two good reviews. How many dollars is he owed for his work today?
Answer:
Step-by-step reasoning process: Hayden gave 3 groups rides, so he is owed 3 * 5 = $15. He drove for 8 hours, so he is owed 15 * 8 = $120. He refilled the gas tank, so he is owed back 17 * 3 = $51. He got two good reviews for a bonus of 2 * 20 = $40. Hayden is owned 15 + 120 + 51 + 40 = $226 for his work today.
So the answer is 226.
