To determine

To discuss the importance of analyzing solutions in the context of real world problems

Explanation of Solution

Given:

x represents the time spent riding a bike, and y represents the distance travelled.

Solution (-1,7)

Let us consider the given solution (-1, 7) = ( x , y ).

Given that x represents the time spent riding a bike and y represents the distance travelled.

Hence, the answer says that the time spent in riding the bike is -1. Time cannot be counted in negative integers.

In real life problems, the negative sign matters. Therefore, one must put on a keen observation on the sign when it comes to real life problems.
