The group thought there was enough food for all 5 group members
to complete the trip, with each person getting the required 6000
calories per day. They discover that 2 of the crates they brought
are missing.
Each crate contains:
• 80 biscuits
• 50 packages of pemmican
• 10 packages of butter and cocoa
Using the map, create a plan for the rest of the trip that includes
taking as many group members as possible to the South Pole, while
sending the rest of the group members directly back to base camp.
Remember that each person must have 6000 calories of food per
day until he or she gets back to base camp.
Be sure to explain how you came up with your plan. Include all
work necessary to support your answer.

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The answer is in the image 

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
