Hi- I am usingspreadsheet put together a times trial for cars. I need to find the speed by dividing distance traveled by time. How do I put this into a formula for multiple cars with different times? Thank you for your help.

Carrie,

assume you have you headers in row 1 of the cells specified below

A1: Car ID B1: time C1: Distance D1: Speed

so in D2 you would put

=C1/B2

then select d2 and copy the cells.

Select d3 and all the cells below D3 that need the formula and then paste. that should fill column D with the speeds for each car listed. If that isn't what you want, post back with a specific example including where the information is located.

if you wanted the average speed for multiple cars in this situation, you would go to the next blank cell in column B and do (assume that is in Row 20

B20: =sum(B2:B19) C20: =sum(C2:C19) D20 =C20/B20

so you can just add up the total distances and the total times and do the division with the sums to get speed.
