Please help. 😪

1. Jack and jill went up the hill to fetch water to fill a 600 gallon tank. Each bucket is 5 gallons. Jack is stronger and is able to carry 2 buckets of water at a time, but jill can only manage one. Also, Jack can complete three trips to the well and back in the time it takes Jill to make two trips. How many trips will Jill make before the tank is filled?

2. The length of a red bus is 4 times the length of an orange car. The length of the orange car is also 3.5 times shorter than the length of a yellow bus. If the yellow bus and red bus are sitting next to each other, what length of the red bus may the yellow bus driver see if the red bus is 48 feet long?

3. Same is stocking up on canned tuna. He got 9 cans at the supermarket and had 5 coupons for 25 cents off a single can per coupon. He paid 30 and got 5.50 in change. How many cents does a can of tuna cost?
