Clue 5
Fractions of a number — the last clue
The radar tower reports that the suspect spent a fraction of their journey flying through high winds. Figure out the total miles in the storm to locate the landing strip.
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 16 = ?
3/6 of 4 = ?
1/8 of 40 = ?
1/4 of 12 = ?
2/4 of 24 = ?
4/10 of 25 = ?
2/8 of 44 = ?
2/4 of 14 = ?
2/5 of 10 = ?
1/5 of 30 = ?
1/3 of 27 = ?
Step 2 — cross out the sentence with each answer
1.The villain performs a dizzying barrel roll, then pours in clean bio fuel.
2.The villain triggers a loud sonic boom, then pours in clean bio fuel.
3.The villain executes a steep cloud dive, then activates the colorful smoke writers.
4.The villain enters a risky tail spin, then charges the wide solar panels.
5.The villain triggers a loud sonic boom, then activates the colorful smoke writers.
6.The villain executes a steep cloud dive, then pours in clean bio fuel.
7.The villain enters a risky tail spin, then ignites the powerful jet engines.
8.The villain performs a dizzying barrel roll, then deploys silent glider wings.
9.The villain completes a perfect loop de loop, then ignites the powerful jet engines.
10.The villain executes a steep cloud dive, then deploys silent glider wings.
