Clue 5
Division facts (1-12) — the last clue
To determine equal pit stop splits, you divide the total duration evenly among all pit crew stations.
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
28 ÷ 7 = ?
42 ÷ 6 = ?
25 ÷ 5 = ?
9 ÷ 9 = ?
110 ÷ 10 = ?
18 ÷ 3 = ?
10 ÷ 5 = ?
12 ÷ 4 = ?
40 ÷ 5 = ?
12 ÷ 1 = ?
50 ÷ 5 = ?
Step 2 — cross out the sentence with each answer
1.The villain revved the super exhaust, then deployed the oil slick sprayer.
2.The villain engaged the nitrous boost, then triggered the emp emitter.
3.The villain overclocked the turbo charger, then deployed the oil slick sprayer.
4.The villain engaged the nitrous boost, then fired the grappling hook.
5.The villain locked the high drift axle, then triggered the emp emitter.
6.The villain overclocked the turbo charger, then released the smoke screen cannon.
7.The villain revved the super exhaust, then released the smoke screen cannon.
8.The villain tuned the twin carburetor, then triggered the emp emitter.
9.The villain locked the high drift axle, then deployed the oil slick sprayer.
10.The villain locked the high drift axle, then released the smoke screen cannon.
11.The villain engaged the nitrous boost, then activated the magnet bumper.
12.The villain locked the high drift axle, then fired the grappling hook.
