Answer this question:There are 30 spaces for each vehicle in a parking lot. A caravan takes up a total of 2 spaces of parking space. How many vehicles can still park if there are 3 caravans currently parking?
The three caravans used up 3x2 = 6 parking spaces in the parking lot. Therefore, 30 - 6 = 24 vehicles can still park in the parking lot.

Answer this question:The number of female students in the school hall is 4 times as many as the number of male students. If there are 29 male students, and there are 29 benches in the hall, at least how many students can sit on each bench for them to all fit in the hall?
The number of female students is 4 times 29: 4 * 29 = 116. There are a total of 29 + 116 = 145 students in the hall. There are 29 benches so each bench should take 145 / 29 = 5 students.
The answer is 5.

Answer this question:Tim rides his bike back and forth to work for each of his 5 workdays. His work is 20 miles away. He also goes for a weekend bike ride of 200 miles. If he can bike at 25 mph how much time does he spend biking a week?
He bikes 20 * 2 = 40 miles each day for work. So he bikes 40 * 5 = 200 miles for work. That means he bikes a total of 200 + 200 = 400 miles for work. So he bikes a total of 400 / 25 = 16 hours.
The answer is 16.
