Question:
d=rt-is there a way to solve these problems using a chart? thanks!
Answer # 7488:
Yes. But it is going to be the biggest multiplication chart ever made. They might even put it in the Smithsonian. Rather than waste your time creating a chart, why don't you learn to use algebra. For example.

Given: D and R, find T

Since D = R × T, then D ÷ R = T

In other words, if you divide the Distance by the Rate you will find the amount of time.

Similarly if you are Given: D and T and asked to find R, then

D ÷ T = R

This is a lot easier than trying to read an multiplication table that will never end.
