Martha spends 10 minutes turning the router off and on again, six times that long on hold with Comcast, and half as much time as she spent on hold yelling at a customer service representative. How much time did Martha spend on these activities total? Give the rationale and then the answer.
Let's think step by step. First find the total time Martha spent on hold: 10 minutes * 6 = 60 minutes. Then find the time she spent yelling: 60 minutes / 2 = 30 minutes. Then add all the amount of time to find the total time: 60 minutes + 30 minutes + 10 minutes = 100 minutes.. The answer is: 100.

Barry and his friend, Jim, went horseback riding across central Texas. They traveled at 5 miles per hour for 7 hours, and then stopped for the evening. The next day, they traveled at 6 miles per hour for 6 hours, and then at half that speed for another three hours, before stopping to rest for the night. On the third and final day, they traveled for 5 hours at 7 miles per hour. In total, how far did they travel, in miles, during their horseback riding trip? Give the rationale and then the answer.
Let's think step by step. On the first day, they traveled 5 * 7 = 35 miles. On the first part of the second day, they traveled 6 * 6 = 36 miles. The second part of the second day, at half their morning speed, they traveled (6 / 2) * 3 = 9 miles. On the final day, they traveled 5 * 7 = 35 miles. In total, they traveled 35 + 36 + 9 + 35 = 115 miles.. The answer is: 115.

It takes 30 minutes to make pizza dough and another 30 minutes in the oven for the pizza to cook. If one batch of pizza dough can make 3 pizzas but the oven can only fit 2 pizzas at a time, how many hours would it take for Camilla to finish making 12 pizzas? Give the rationale and then the answer.
Let's think step by step. Camilla needs 12 / 3 = 4 batches of pizza dough. 4 batches of pizza would require 30 x 4 = 120 minutes. Camilla needs to bake the pizzas 12 / 2 = 6 times. 6 times in the oven would take 30 x 6 = 180 minutes. Altogether, it would take 120 + 180 = 300 minutes to finish making 12 pizzas. 300 minutes is 300 / 60 = 5 hours.. The answer is: 5.
