Two athletes A and B are moving with a speed of 4m/s and 18km/h respectively. Who is running faster?
Answer posted by FauxPas 3+ months ago: Make the unit of measurement the same, and then you can compare. 60 * 60 seconds in an hour. 1000 meters in a kilometre. speed2 = 18kmh = 1000*18 / (60*60) ms
