well, distance (d)=speed (s) x time (t)
so d=42 x 1.5 (hr and a half =90 mins)
which comes out at 63km/h

When working with values that have different units, it's best to write the whole thing out while preserving the units and using conversion factors. The basic formula is to multiply velocity by time to get displacement.
x = vt = (42 km/hr)(90 min)(1 hr / 60 min) = 63 km

90/60*42=63
