Question

Which expression can be used to change 75 kilometers per hour to meters per minute?

Answer 1

It helps you:

`1(km)/(h)=1\cdot(1000m)/(3600s)=(10)/(36)(m)/(s)<u></u>`

`75(km)/(h)=75\cdot(1000m)/(3600s)=(750\cdot10)/(36)(m)/(s)=(750)/(36)(m)/(s)~=20,83(m)/(s)`

Answer 2

When you say "Which...", does that mean you're looking at a list of choices
and not sharing it ?


To change (kilometers/hour) to (meters/minute), multiply (kilometers/hour) by

(1,000 meters/kilometer) x (hour/60 minutes).

Both of those fractions are equal to ' 1 ', so the process doesn't change the
original quantity, just its units.
