Question 389482: a bus travels alone a highway at a constant rate of 55 miles per hour. How far does the bus travel in 3 hours and 24 minutes? Answer by gwendolyn(128) (Show Source):
You can put this solution on YOUR website! We use the formula distance = rate * time. The only trick is using consistent units since 3 hours and 24 minutes is a mixture of hours and minutes.
Let's change that into an improper fraction using the fact that there are 60 minutes in an hour. 3 hours and 24 minutes is the same as 3 and 24/60 hours.
So:
3 and 24/60 = 3*(60/60) and 24/60
180/60 + 24/60 = 204/60 hours
Now we can use the formula:
distance = 55 * 204/60
distance = 187 miles
