Answer:

Units: ( km / min) * (min / hr) = km / hr

(The units for minutes cancel each other out)

Speed = (68 km / 33 min) * (60 min / 1 hr) = 123.6 km/hr

Explanation:

Good question - this is going to be a unit conversion-type question. What we have is two different units of time, which we'll have to convert between, knowing the fact that 60 minutes = 1 hour.

Hope that helps!
