Challenger: Linear Inequalities

Adapted from wiley.com

Two speed boats are racing along a section of a lake.
The speed limit along this section of the lake is 50 km/h. Ray is travelling 6 km/h faster than Stephen and the sum of the speeds at which they are travelling is at a speed greater than 100 km/h.

a. Write an inequality and solve it to describe all possible speeds that Stephen could be travelling at.
b. Verify if Stephen's lowest possible speed was over the speed limit.
c. The coast guard issued a warning to Ray for exceeding the speed limit on the lake. Explain why the police were justified in issuing a warning to Ray.

Different Faces of Algebra

The total length of 4 roads is (3x - 1) km.
What are the possible lengths of the 4 roads in kilometres?

e.g. The length of the 4 roads are: x km, x km, x-7 km, 6 km
Check: x + x + (x - 7) + 6 = 3x - 1

Enter your suggested lengths in comments.
