APPROXIMATELY 30 MILES.
let the total distance be x.
day 1=x/4.
day 2=1/4*3x/4.
day 3=2/5*1/4*3x/4.
day 4=1/2*2/5*1/4*3x/4.
day 5=14.
therefore day1 +2+3+4+5=x
=> x/4+1/4*3x/4+2/5*1/4*3x/4+1/2*2/5*1/4*3x/4+14=x
LCM=160.
75*x=2240.
x~~30 miles

After some rapid calculations, Margaret was able to figure out how many campers were going to the picnic. Can you?

Camp Pineveiw's cook, Margaret Johnson, was just about to begin preparing the picnic lunch for all the campers. She already knew she needed to fill 55 bowls of the same size and capacity with the same amount of food. When she was done, she decided to read the guidelines for the picnic, just out of curiosity. The guidelines said:

  1. Every camper gets their own bowl of soup.
  2. Every two campers will get one bowl of spaghetti to share.
  3. Every three campers will get one bowl of salad to share.
  4. All campers are required to have their own helping of salad, spaghetti, and soup.

How many candies did Mr. Kandala have left when the doorbell rang?

Halloween was almost over, and Mr. Kandala had less than 20 candies left. When the doorbell rang, he thought he would give all the candies away. When he opened the door, there were two trick or treaters. He wanted to give away the candies evenly, but he noticed that when he divided the candies in two, there was one left over. At that point, he saw another trick or treater behind the first two. He tried to divide the candies evenly among the three of them, but again one was left over. Finally, another trick or treater came to his door, making it four trick or treaters altogether. Mr. Kandala still had one candy left over after dividing the left over candies in fours.
