Answer :

Steve races to the nearest taco stand at lunchtime and sees that his pedometer recorded his peak speed at 76.7 cm/s. What was Steve's peak speed in kilometers per hour?

Explanation:

1 Km=100×1000 cm

1 hour=60×60=3600 sec

Now

1  cm=10−5 km\ cm=10^{-5}\ km\\ cm=10−5 km

1 sec=0.00027777777 hour

Now

speed=76.7sec cm​=0.0002777777776.7×10−5​hour km​=2.7612 km hour−1
