Question

Inequalities: To qualify for the championship, a runner must complete the race in no more than 45 minutes. Use t to represent the time (in minutes) of a runner who qualifies for the championship. The vehicle's fuel efficiency is at least 40 miles per gallon. Use f to represent the vehicle's fuel efficiency (in miles per gallon).

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

t = time

f = fuel efficiency

inequalities = ?

Step 02:

1. time

t ≤ 45 min

2. fuel efficiency

f ≥ 40 miles per gallon

The answer is:

1. time

t ≤ 45 min

2. fuel efficiency

f ≥ 40 miles per gallon
