The bus drives 66 km at an average speed of 24 km/h. How long does the journey take?
rewona [7]

Answer:

2.75 hours

Step-by-step explanation:

Speed is 24km per hour (\frac{24km}{1hour}), and the bus covered 66km.

We need to get a value of <em>km</em> with the rate (24/1) and distance (66) given.

We get:  \frac{1hour}{24km} *66km.  

The km cancel out, leaving us with 66/24 hours, or 2.75 hours.
