An airplane flies at a rate of 356 km/h . If the plane travels a total distance of 1424 km, how long was it in the air? Answer by nerdybill(1128) (Show Source):
You can put this solution on YOUR website! If the plane was flying at the speed of 356 km/h we can rewrite that as:
1/356 h/km
that's read: "one hour per 356 km"
.
Now,
1424 km * 1/356 h/km
= 1424/356 hours
= 4 hours
