Question: Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?
Answer with step-by-step thinking: Elrond was able to get 20 x 2 = 40 tulips. Therefore, the total number of tulips they were able to get is 40 + 20 = 60.
So the answer is 60.


Question: Tim has 30 less apples than Martha, and Harry has half as many apples as Tim. If Martha has 68 apples, how many apples does Harry have?
Answer with step-by-step thinking: Tim has 68 - 30 = 38 apples. Harry has 38 / 2 = 19 apples.
So the answer is 19.


Question: Tim is stuck in traffic for twice as long as he was driving. He drove 5 hours. How long was the trip?
Answer with step-by-step thinking:
He was stuck in traffic for 5 * 2 = 10 hours. So his trip took 10 + 5 = 15 hours.
So the answer is 15.
