Answer:
2,769 boxes in 1 hour.
Step-by-step explanation:
The time taken by a machine to make a box = seconds = 1.3 seconds
We have to calculate how many boxes can the machine make in 1 hour.
As we know 60 seconds = 1 minute and 60 minute = 1 hour
∵ 1.3 seconds taken by the machine to make = 1 box
∴ in one minute machine can make boxes =
= 46.15 boxes
∴ in 1 hour machine can make boxes = 46.15 × 60
= 2,769 boxes
Machine can make 2,769 boxes in 1 hour.

Answer:
i. Colonel is about 201 feet away from the fire.
ii. Sarge is about 125 feet away from the fire.
Step-by-step explanation:
Let the Colonel's location be represented by A, the Sarge's by B and that of campfire by C.
The total angle at the campfire from both the Colonel and Sarge = +
=
Thus,

=
cross multiply,
b =
= 200.8993
Colonel is about 201 feet away from the fire.
ii. Sarge's distance from the campfire (a), can be determined by applying the sine rule;
=

=
cross multiply,
a =
= 124.8073
Sarge is about 125 feet away from the fire.
