That's pretty simple division.  Hint, convert 35 cm/year to m/year.

• Change m to cm then divide...

85000 /35 = 2429 years to the nearest year.

• Work out how many centimetres are in 850 metres.

Then divide that figure by 35 to tell you how many centimetres per year.

• 850 meters is 85,000 centimeters.

If it's 35 centimeters a year .. divide 85,000 by 35.

Giving 2428.57 (rounded to two decimal places).

So it will have eroded that much somwhere between 2,428 and 2,429 years.

So the answer is 2,429 years.

• This seems to be a simple math problem which can be solved by dividing 850 by 35. The answer is about 24 plus years. At the rate of 35 cm per year, 24 years would mean 840 cm and, at the rate of about 3 cm per month, 3 more months would add 9 cm for a total of 849 cm.

Except that it's 850m and 35cm .. so it's NOT that simple .. you need to multiply by 100.

• Change 850 meters into cm and divide by 35 and so (850*100)/35 = about 2429 years

• 35cm = 0.35m

t = 850m * 1yr/0.35m

t = 850/0.35 yr

t = 2,428.5714285714 yr

~ 2,429 years <––––––
