nicely, you start up by using dividing the kilometers by using the time, so as which you recognize what share km she did for one minute, so thats: 3.2/20 = 0.sixteen km/min (a million) then, you are able to desire to remodel the km/min to m/min. nicely, you recognize that there are one thousand m according to a million km (if doubtful, you're able to understand that kilo means thousand). so, you multiply the kilometers with the quantity of meters there are according to one kilometer and you get 0.sixteen*one thousand = 160m/min (2) to get the kilometers according to hour, you besides mght use (a million). you recognize that there are 60 min according to hour, so which you're taking the value according to minute and multiply it with 60 to confirm the km/hr 0.sixteen*60 = 9.6 km/hr (3) you additionally can clean up the final one with none previous calculation in case you recognize that 60 min is 3x20 min, so which you in elementary terms would desire to multiply the value of three.2km/20 min with 3 3.2*3=9.6 km/hr (3')

1 km/minute = 60 km/hour
easiest way, google 1.5 km/minute to km/hour

Multiply by 60 minutes/hour. Be sure to carry your units so the minutes cancel, or you may end up dividing instead!
Divide by 60.
km/min * (60min/1hr) = 60 km/hr
multiple by something which cancels the min, in this case there are 60min in one hour , or in other words (60min / 1hour)
300 (km/min) * (60min / 1hour) = 18000 km/hr
