Clue 1

Addition

Chief Joshua Dax Zeno needs to count the extra seatbelts left in the main cabin. Adding these supplies up will reveal our first major clue about the hijacker's gear.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

Clue 5

Fractions of a number — the last clue

Only a small fraction of the emergency escape pods are still active. Calculating this fraction of the pods lets us pinpoint where the suspect is hiding.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

6/8 of 4 = ?

1/4 of 40 = ?

2/4 of 10 = ?

1/3 of 3 = ?

3/5 of 15 = ?

4/8 of 16 = ?

1/10 of 110 = ?

2/4 of 4 = ?

1/2 of 12 = ?

5/10 of 24 = ?

1/8 of 32 = ?

Step 2 — cross out the sentence with each answer

1.The villain dims the cabin lights, then swings on the cargo rope.

2.The villain disables the radar cabin, then deploys the emergency chute.

3.The villain jams the radio tower, then swings on the cargo rope.

4.The villain disables the radar cabin, then swings on the cargo rope.

5.The villain jams the radio tower, then escapes down the slide.

6.The villain disables the radar cabin, then escapes down the slide.

7.The villain locks the cockpit doors, then escapes down the slide.

8.The villain diverts the fuel valves, then leaps onto a cloud glider.

9.The villain dims the cabin lights, then zooms away on a scooter.

10.The villain locks the cockpit doors, then swings on the cargo rope.

11.The villain jams the radio tower, then zooms away on a scooter.

12.The villain diverts the fuel valves, then deploys the emergency chute.
