Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

### The track at Oak Middle School is 1/4 of a mile for each lap. Jacob walked around the track and completed 7 laps in 30 minutes. What is the unit rate of Jacob's speed?

I edited the question to show 1/4 mile. Jacob walked 7X1/4 that is 1 and 1/4 miles. 1.25 / 30 = .041 miles in 1/2 hr. .041 x 2 is .082 miles an hour.

### Strap broken on timex heart rate monitor watch 30 lap ironman triathlon need a replacement

Hi, Almost any large dealer like Wal-Mart, Sears, or Target will have Timex replacement straps and bands for most popular watches and monitors. Sometimes a local Authorized Dealer will have specialized products that the department stores don't even carry without ordering.

I have had good luck with Wal-Mart on watch accessories. I've also ordered straight from Timex in Little Rock, Arkansas, ph. 1-800-448-4639, but it usually takes more time for just parts.

Thanks, Bill

### How can i recall multiple laps during a run?

The Timex Ironman 30 Lap also has a stopwatch that can be used to keep track of split times for racing sports like running or cycling. Press the "Mode" button until the display shows "Chrono," then press and hold the "Set/Recall" button. To start the timer, press the "Start/Split" button. It will continue to run even if you exit to another mode. Pressing the "Stop/Reset" button will stop the chronograph. To record a split time, press the "Start/Split" button again while the timer is running. To see your split times, press the "Set/Recall" button while the watch is in Chrono mode. You can then scroll through the various splits with the plus and minus keys. Press "Set/Recall" again to exit display mode and return to the timer.
