[Question]: Sadie, Ariana and Sarah are running a relay race. Each part of the race is a different length and covers different terrain. It takes Sadie 2 hours to run through the forest at an average speed of 3 miles per hour. Ariana sprints across the open field on her section at 6 miles per hour for half an hour. If Sarah runs along the beach at four miles per hour and their total time for the race is four and half hours, what is the total distance of the race?
[Answer]: Sadie ran for 3 miles / hour * 2 hour = 6 miles. Ariana covered a distance of 6 miles / hour * (1 / 2) hour = 3 miles. Sarah ran for 4.5 hours 2 hours 0.5 hours = 2 hours. In this time, Sarah traveled a distance of 4 miles / hour * 2 hours = 8 miles. The total distance for the race was 6 miles + 3 miles + 8 miles = 17 miles.
So the answer is 17.

[Question]: Drew is reseeding his lawn with grass seed. One bag of grass seed covers 250 square feet of lawn. His lawn is 22 feet from the house to the curb and 36 feet from side to side. He bought four bags of seed. How many extra square feet could the leftover grass seed cover after Drew reseeds his lawn?
[Answer]: Drew's lawn is 22 * 36 = 792 square feet. He bought enough grass seed to cover 250 * 4 = 1000 square feet. Thus, the leftover grass seed can cover 1000 - 792 = 208 square feet.
So the answer is 208.

[Question]: At a shop in Japan, women's T-shirts are sold every 30 minutes for $18, and men's T-shirts are sold every 40 minutes for $15. This shop is open from 10 am until 10 pm. How much does the shop earn selling T-shirts per week?
[Answer]:
First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T - shirts sold per day. The shop earns 24 * $18 = $432 selling women's T - shirts per day. Similarly, 720 / 40 = 18 men's T - shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T - shirts per day. The shop earns $432 + $270 = $702 per day selling T - shirts. The shop earns $702 * 7 = $4914 per week.
So the answer is 4914.
