Clue 1

Fractions of a number

We retrieved the entrance scanner logs from the stadium airlock. Solving these multi-step flight calculations reveals gear we can rule out.

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 2

Bar model word problems

The power grid monitor generated bar models showing thrust outputs. Compare these visual power models to isolate the suspect's dominant foot.

Draw a bar model to solve each word problem. Its answer reveals a letter — write the letters in the boxes to fill in the missing word.

Clue 5

Fractions of a number — the last clue

Analyzing fractional amounts of remaining booster fuel gives us our final piece of trace evidence.

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
1/2 of 22 = ?
2/4 of 10 = ?
2/4 of 14 = ?
3/6 of 16 = ?
1/8 of 32 = ?
2/10 of 50 = ?
1/5 of 15 = ?
1/3 of 3 = ?
1/5 of 45 = ?
5/10 of 4 = ?
3/5 of 20 = ?
Step 2 — cross out the sentence with each answer
1.The villain curved a shot through gravity waves, then deployed a gravity shield.
2.The villain directed a photon header into orbit, then ignited a nebula booster.
3.The villain directed a photon header into orbit, then charged up starlight gloves.
4.The villain fired a plasma kick across the stadium, then deployed a gravity shield.
5.The villain warped past defense drones, then activated solar cleats for speed.
6.The villain pulled the ball with a tractor beam, then deployed a gravity shield.
7.The villain curved a shot through gravity waves, then ignited a nebula booster.
8.The villain fired a plasma kick across the stadium, then calibrated an ion visor.
9.The villain warped past defense drones, then charged up starlight gloves.
10.The villain directed a photon header into orbit, then calibrated an ion visor.
11.The villain fired a plasma kick across the stadium, then activated solar cleats for speed.
12.The villain fired a plasma kick across the stadium, then charged up starlight gloves.
