Two cars drive the same distance at
different speeds. Which car takes more time to travel
the distance?
The question is asking us to figure
out which car will take more time to travel the distance shown. Let’s start by recalling what speed
is. The speed of an object is the
distance that the object travels divided by the time that the object travels
for. In this question, we are told that
both cars travel the same distance.
Let’s take a look at the
relationship between speed, distance, and time. We see that in the formula for
speed, speed is equal to a fraction. The distance is the numerator for
the fraction, and time is the denominator for the fraction. We know that both of the
numerators, the distance that the cars travel, are equal. When the numerators are equal for
two fractions, the smaller fraction will be the fraction that has the larger
denominator.
In the formula for speed, the time
that the car travels for is the denominator. This means that the lesser speed
must be the speed of the car that travels for a greater time. The question asks which car takes
more time to travel the distance. We see that the correct choice is
that the car with less speed takes more time to travel the distance.
