Answer
The total number of occupants in Capsule 24 is calculated as follows:
Adults: 18
Children: 7
Senior Citizens: 5
Total for Capsule 24 = 18 + 7 + 5 = 30
The total number of occupants in Capsule 30 is calculated as follows:
Adults: 10
Children: 1
Senior Citizens: 5
Total for Capsule 30 = 10 + 1 + 5 = 16
Hence, the total number of occupants for both capsules = 30 + 16 = 46.

Answer
The formula to calculate the circumference is:
Circumference=2×π×radius
Substituting the values,
Circumference=2×3.142×197
Calculating this gives:
Circumference=1237.49 feet
Step 3
4.1.2 (b) Hence, calculate the distance (to the nearest metre) on the circumference between any TWO capsules right next to each other

Answer
If the total circumference is 1237.49 feet and there are 32 capsules,
The distance between two adjacent capsules is given by:
Distance=Number of CapsulesCircumference=321237.49
