Question

Answer 1

Answer:

1.47 Years  ( 1.5 Years)

Step-by-step explanation:

at the continued rate of extraction , in how many years is the coal from the folen mine likely to run out

Data is given in picture

Remaining coal  (millions of tonnes) = 68.27

Extraction (000s  tonnes) per year = 46324

number of years is the coal from the folen mine likely to run out

= Remaining coal / (extraction per Year)

= 68.27 * 10⁶ / 46324 * 10³

= 68270/46324

= 1.47  (1.5 Years)

in 1.47 (1.5) years coal from folen mine is likely to run out.
