Answer:
2.75 hours
Step-by-step explanation:
Speed is 24km per hour ([tex]\frac{24km}{1hour}[/tex]), and the bus covered 66km.
We need to get a value of km with the rate (24/1) and distance (66) given.
We get: [tex]\frac{1hour}{24km} *66km[/tex].
The km cancel out, leaving us with 66/24 hours, or 2.75 hours.
