Question

Suppose you ride your bike uphill to work at a speed of at least x mph. Going downhill on the way home, your speed is 5 mph faster. Your average speed to and from work is at least 12 mph. Which is the correct inequality to model the situation?



THE ANSWER IS C
1/x + 1/x+5 greater than or equal to 2/12
i guessed :)

Answer 1

The correct inequality to model the situation is x ≥ 19/2

What is inequality?

An inequality is an algebraic expression of two quantities that are unequal.

Analysis:

Total speed = x + x+5 = 2x+5

Average speed = 2x+5/2 ≥ 12

2x+5 ≥ 24

2x ≥ 24-5

2x ≥ 19

x ≥ 19/2 mph
