Answer:
Speed = 50km/1.25 Hours which leads to Speed = 40 km/h
So now what we have:
40 km/h = Distance/3.45Hours
in order to fix this we now must multiply both side by 3.45, why? Magic! nah just kidding, we want to isolate the Distance to be the only factor on one side of the equation in order to realise what it’s value is, therefore:
Distance = 40(km/h) x 3.45(h) which leads to 138 km.
Notice that not only the numbers are multiplied but the units of measurement too. Due to the speed being km divided by hours, and we’re multiplying them by hours too we find the hour units are cancelled (do 5 divided by 2 then times by 2, same answer, the factor is cancelled out!).
