WebYes, instead of multiplying by time you can just plug the numbers into the equation: time = distance / rate (speed). In this case it would be: time = 720m / 3m per sec When you divide 720m by 3m/s the meters cancels out and you are then left with time which would be 240 seconds. This equation though is just a manipulation of rate = distance/time. WebCalculate its speed in m/s. First, convert the distance from kilometres (km) to metres (m): 1 km = 1,000 m This means that 72 km = 72,000 m Then convert the time from hours (h) to seconds (s):... healthcare ambetter
