Answer: The worm slithers 48 inches in an hour. The snail slithers 52 inches in an hour.
If we start by making both the races into equations we get 5w+4s=448 inch and 2w+3s=252 inch. If we then add both the equations together we get 7w+7s=700 inch. Then we divide it all to get 1w+1s=100 inch. Then we can subtract the second race from the first to get 3w+1s=196 inch. We now know that 2w=96 inch, and can therefor divide whit 2 to find out w=48. We can then figure out how fast the snail is moving by multiplying 48 whit w and dividing the answer by s.
