2. How many minutes will it take to catch up with the team?

Let's say the meeting time is x minutes and the distance is equal: 935*X=5*30+5*X, X= 1/62 minutes. It is estimated that your walking speed is not right. You have to walk at least 60 steps to 30 meters a minute. It's not that slow!

3. Find the height of the cylindrical water storage bucket.

First calculate the volume of the effluent: 8 * 5 *1.2/(1+11) = 44.

Recalculated height: 44/8*5/4=6.875.

4,6000+50=6050
