[Question]Nida has 50 chocolates in which some are in 3 filled boxes and 5 pieces are not in a box. Her friend brought 25 pieces of chocolates. If all chocolates must be placed in a box, how many more boxes do they need?

Q: Brad's car broke down on an isolated road. At the time, Brad was traveling with Jim and Marcus. So, the three decided to push the car back into town, which was 10 miles away. For the first three miles, Brad steered as Jim and Marcus pushed at a speed of 6 miles per hour. Then, for the next 3 miles, Jim steered, as Brad and Marcus pushed at a speed of 3 miles per hour. For the last four miles, Marcus steered as Brad and Jim pushed at a speed of 8 miles per hour. How long did it take, in hours, to push the car back to town?
A: Three miles at 6 miles per hour is 3 / 6 = 1 / 2 hours. Then, 3 miles at 3 miles per hour is 3 / 3 = 1 hour. The last 4 miles at 8 miles per hour is 4 / 8 = 1 / 2 hour. In total, it took them 1 / 2 + 1 + 1 / 2 = 2 hours to push the car back to town. The answer is 2.
Question: James drives 30 mph for half an hour and then twice as long for twice the speed. How far did he drive in total?
Answer:
His first drive was 30 * .5 = 15 miles. The next leg was .5 * 2 = 1 hour. The speed of the trip was 30 * 2 = 60 mph. So he drove 60 * 1 = 60 miles. So in total he drove 60 + 15 = 75 miles. The answer is 75.
