400 m in 8 hours
200 m in 4 hours
100 m in 2 hours
50 m in 1 hour
His average speed is 50mph
The answer is 88 because if you add 5+3 and then multiply by 11, you would equal out to 88 dogs and cats
After scout fixed the little old lady's bicycle horn, scout said Beep Repaired.
You can do this 2 ways, one is knowing the special right triangles called triplets. An example of a triplet would be 3-4-5 where the largest value is the hypotenuse. In this example, the other 2 sides are 3 and 4 and the missing side is the hypotenuse, so using the knowledge of triplets, we can find that the hypotenuse is 5.
algebraically, we can use the Pythagorean theorem; a^2+b^2=c^2 where a and b are the opposite and adjacent and where c is the hypotenuse. We can then substitute in the values to get : 3^2 + 4^2 = c^2. When simplified, we get 9+16=c^2. Simplify further, and get 25=c^2. Now we Square root both sides to solve for C. Finally, we get C=5. Your missing side is 5.
