To qualify for the championship, a runner must complete the race in less than 40 miles. Use t to represent the time of a runner who qualifies for the championship

The inequality which represents the situation is .

Step-by-step explanation:

Given:

Number of miles to complete the race = 40 miles.

We need to write the inequality to represent the situation.

Solution:

Let 't' represent the time of a runner who qualifies for the championship.

SO now we can say that;

time of a runner who qualifies for the championship should be less than Number of miles to complete the race.

framing in equation form we get;

Hence The inequality which represents the situation is .
