I am doing the race time entry for a 5K Pump and Run. The racers lift wieghts and the number of reps are multiplied by 30 seconds and then that total is deducted off of their race time. I am having a hard time setting up a formula that would take the number of reps and multiply them by 30 seconds. I want the total to show as hh:mm:ss

Can anyone help? The race is Saturday, June 5th and I need to get this done ASAP!!! Sorry for waiting til the last minute!

Thanks for any help.
