Step-by-step explanation:
Time for equipment elevator = 11 seconds + 27 seconds = 38
Time for elevator for miners = 27 seconds
Speed of equipment Elevator = 7 feet/ sec
Speed of Miner elevator = 16 feet/ sec
Distance traveled by Equipment Elevator = Speed * time
= 7 * 38 = 266
Distance traveled by Miner Elevator = Speed * time
= 16 * 11 = 176
266 > 176
Therefore, The Equipment Elevator is deeper than the Miner Elevator
Depth of Equipment Elevator = 266m
Depth of Miner Elevator = 176m

If Reducing 2 men will bbe enough too finish the work in 10 days
For rate of work use the formualar
rate of work = quantity of work / duration
10 men can do the work at a rate of = 1 / 8
x men can do same work at a rate of = 1 / 10
x * ( 1 / 8 ) = 10 * ( 1 / 10 )
x = 1 * 8 = 8
therefore 8 men can do the work in 10 days
number of men reduced = 10 men - 8 men = 2 men
Hope it helped
Answer:

Step-by-step explanation:
Step one:
given
cost per drive= $20
additional fee per person= $4
let the number of persons be p
and the total cost be C
The total cost function is expressed as

Step two:
Required:
<u><em>We want to make P subject of the cost function </em></u>
Take 20 to the other side we have
C-20=4p
divide through by 4
P=C-20/4
simplify
P=C/4-5
