Since you posted this in the "Parent's Place", it would be nice to know what grade your son/daughter is in so that we can help you help him/her appropriately.
What course is he/she taking?
To start off, find out if he/she is familiar with the equation
d=rt
We will be using that equation to solve this problem.
