Question
A car travels 240 km in 4 hours. How long does it take the same car to travel 480 km?
Answer 1
We can set up a proportion to find out how long it takes the car to travel 480 km:
240 km / 4 hours = 480 km / x hours
Simplifying the equation, we get:
x hours = (480 km * 4 hours) / 240 km
x hours = 8 hours
Therefore, it takes the same car 8 hours to travel 480 km.
Answer 2
Unit Rate
We can also use the unit rate of distance traveled per hour to find out how long it takes the car to travel 480 km. The unit rate is:
240 km / 4 hours = 60 km per hour
Therefore, it takes the car 8 hours to travel 480 km because 60 km per hour * 8 hours = 480 km.
