Clue 1

Subtraction

Chief Joshua Dax Zeno inspects the emergency locker. We started with sixty flares but some were stolen. Subtracting the remaining flares reveals how many the culprit took to light their escape route.

Clue 2

Fractions of a number

The fireplane crash broke the cockpit control panels. Chief Zeno notices that only a small fraction of the forty-eight backup indicator lights are still flashing. We must calculate this fraction to reboot the radar.

Clue 3

Multiplication facts (1-12)

A parachute drop landed rescue supplies in a grid on the forest floor. Chief Zeno counts the rows and columns. We multiply these groups together to find the total number of walkie-talkies available.

Clue 4

Addition

We need to check the remaining fuel levels in both wing tanks. Adding the gallons from the left wing to the gallons in the right wing gives Chief Zeno the total range of the escape plane.

Clue 5

Fractions of a number — the last clue

The copilot finds a torn flight manual with sixty-four pages in total. The chief determines that a fraction of the manual contains the secret bypass codes. Calculating this fraction unlocks the culprit's profile.

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

3/6 of 22 = ?

1/10 of 10 = ?

1/6 of 48 = ?

4/10 of 15 = ?

8/10 of 5 = ?

1/3 of 27 = ?

2/3 of 15 = ?

1/4 of 12 = ?

3/6 of 4 = ?

5/10 of 14 = ?

2/3 of 18 = ?

Step 2 — cross out the sentence with each answer

1.The villain escaped on a smokebuster flight jet, then activated a night-vision visor.

2.The villain zipped away on a glide rescue wing, then activated a night-vision visor.

3.The villain ran while operating a scout drone, then scanned the woods with a thermal radar kit.

4.The villain took off in a turbo rotor copter, then scaled the cliff using a super-grip grapple.

5.The villain took off in a turbo rotor copter, then cleared the path with a mega foam blaster.

6.The villain fled in a heavy water bomber, then scanned the woods with a thermal radar kit.

7.The villain took off in a turbo rotor copter, then broke open the cockpit with a titanium crowbar.

8.The villain zipped away on a glide rescue wing, then cleared the path with a mega foam blaster.

9.The villain fled in a heavy water bomber, then cleared the path with a mega foam blaster.

10.The villain ran while operating a scout drone, then scaled the cliff using a super-grip grapple.

11.The villain fled in a heavy water bomber, then broke open the cockpit with a titanium crowbar.

12.The villain fled in a heavy water bomber, then scaled the cliff using a super-grip grapple.
