You just need to multiply the value by 5.
Answer: 14.8
Explanation: You’re trying to find the hypotenuse using the two legs that you have. The formula to find hypotenuse is a^2+b^2=c^2. You are trying to find c^2. So it would be 10^2+11^2=c^2. 10^2 is 100 and 11^2 is 121 and 100+121 is 221. Then you would square root 221 and get 14.8 for the hypotenuse.
There are 12 inches in one foot. If it rains 2 inches per hour and we need one foot we need to look for a number that can be multiplied by 2 to get 12.
