A car travels 240 kilometers in
three hours with uniform velocity. If the car continues at the same
speed, what distance will be covered in five hours?
There are several ways we could
approach this problem. Since the car travels with uniform
velocity, one way would be to calculate this velocity by dividing the distance by
the time. We are told that the car travels
240 kilometers in three hours. Since 240 divided by three is 80,
the velocity the car is traveling at is 80 kilometers per hour.
We are asked to calculate the
distance that will be covered in five hours if the car continues at the same speed
or velocity. We can calculate this by
multiplying 80 kilometers per hour by five hours. This is equal to 400
kilometers. If the car continues at the same
speed, it will have covered a distance of 400 kilometers in five hours.
An alternative method would be to
set up a table involving the time in hours and distance in kilometers as shown. We know that in three hours the car
traveled a distance of 240 kilometers. Dividing both of these numbers by
three, we see that the car would have traveled 80 kilometers in one hour. We can then multiply both values by
five to prove that the car would have traveled a distance of 400 kilometers in five
hours.
