Q: Mr. Isaac rides his bicycle at the rate of 10 miles per hour for 30 minutes. If he rides for another 15 miles, rests for 30 minutes, and then covers the remaining distance of 20 miles, what's the total time in minutes took to travel the whole journey?
A: If in one hour he covers 10 miles and rides for 15 miles at the rate of 10 miles per hour, then the time taken for the 15 miles will be 15 / 10 = 1.5 hours. The time in minutes is 1.5 * 60 = 90 minutes. The time taken for the remaining 20 miles at a rate of 10 miles per hour is 20 / 10 = 2 hours. The time in minutes is 2 * 60 = 120 minutes. The total time taken for the whole journey is the first 30 minutes + 90 + 30 minutes for resting + 120 minutes = 270 minutes. The answer is 270.
Question: Lolita has 54000 strawberry seeds. In each planting zone, 3123 seeds will be used. If she will accumulate 7 planting zones, how many strawberry seeds will remain?
Answer: The total amount of seeds used in the planting zones is 3123 x 7 = 21861. The total amount of seeds left after planting is 54000 - 21861 = 32139. The answer is 32139.
[Question]The dog toys Samantha buys for her dog are "buy one get one half off" and all cost $12.00 each. She buys 4 toys. How much does she spend on dog toys?
[Answer]If she buys 1 toy at $12.00 she gets the 2nd toy 1 / 2 off, the 2nd toy is 12 * .5 = $6.00. 1 full - priced toy is $12.00 and 1 / 2 priced toy is $6.00 so these 2 toys come to 12 + 6 = $18.00. She buys 2 more toys that are "buy one get one 1 / 2 off" so all total she spends 2 * 18 = $36.00. The answer is 36.
Q: Jaydee can type 38 words in a minute. How many hours will he take to finish typing a research paper with 4560 words?

Question: Diane bakes four trays with 25 gingerbreads in each tray and three trays with 20 gingerbreads in each tray. How many gingerbreads does Diane bake?
Answer: Four trays have 4 x 25 = 100 gingerbreads. And three trays have 3 x 20 = 60 gingerbreads. Therefore, Diane bakes 100 + 60 = 160 gingerbreads. The answer is 160.
Q: Mr Fletcher hired 2 men to dig a well in his compound. They worked for 10 hours on the first day, 8 hours on the second day and finished the job on the third day after working 15 hours. If Mr Fletcher paid each of them $10 per hour of work, calculate the total amount of money they received altogether?
A:
The total number of hours each worker works in the first 2 days is 10 + 8 = 18 hours. Since they completed the job in three days, each was compensated for 18 + 15 = 33 hours of work. Mr Fletcher paid each of the workers $10 per hour of work, meaning for 33 hours, each of the workers received 33 * $10 = $330. Since they were two workers, the total amount they received all together after each was paid $330 is $330 * 2 = $660. The answer is 660.
