The chilean miners that were stuck underground for 69 days in oct 2010 were rescued using a new and innovative construction. the 'shuttle', which can only transport one person at a time, travels at a speed of 70 cm/s. how far down were the miners if it took them 16 min to get each miner out?

Each miner was 672 meters below the surface.

Step-by-step explanation:

The speed of the shuttle = 70 cm/s

Time taken to get each miner out = 16 minutes

Converting 16 minutes into seconds, we get

the total time taken by shuttle to reach the miner = 16 x 60s = 960 s

So, Total Distance traveled by shuttle =  Speed of the shuttle X Total time taken

or, Total distance = 70 cm/s x 960 s = 67,200 cm

As, 100 cm = 1 meter

⇒67,200 cm = (67,200 / 100) meters = 672 m

or, D = 672 m

Hence, each miner was 672 meters below the surface.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
