Question

On average, a dog runs 5.5 times faster than a child. Which equation can be used to find s, the speed of a dog, given r, the speed of the child ?

Answer 1

s = 5.5r

Explanation:

Since a dog can run 5.5 times faster than a child that means that the dog's speed (s) should be equal to 5.5 times the speed of the child (r).

Therefore,

speed of dog (s) = 5.5 × speed of child (r)
