- Hence B
Answer:
180 pages
Step-by-step explanation:
Let
x = total number of pages
Monday + Tuesday + Wednesday
2/15x + 1/3x + 2/9x
= (6x+15x+10x)/45
= 31/45x
Thursday
x - 31/45x
= (45x-31x)/45
= 14/45x
3/4 of 14/45x
= 3/4 * 14/45x
= 42/180x
Total pages read = 31/45x + 42/180x
= (124x+42x)/180
= 166/180x
If he still has 14 pages left to read on Friday
Total read from Monday to Thursday + Friday
x = 166/180x + 14
x - 166/180x = 14
(180x-166x)/180 = 14
14/180x = 14
x = 14 ÷ 14/180
x = 14 × 180/14
x = 180 pages

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Equipment elevator :
Descent rate = 5 ft/s
Miner's elevator :
Descent rate = 17 ft/s
Position of elevator after 16 seconds
Total descent time of equipment elevator = (29 + 16) = 45 seconds
Position after 45 Seconds :
Descent rate * time
5ft/s * 45s = 225 ft
Descent time of Miner's elevator = 16 seconds
Position after 16 Seconds :
Descent rate * time
17ft/s * 16s = 272 fts
Miner's elevator is deeper = 272 feets > 225 fts
Position of equipment elevator relative to the surface = - 225fts
