A glacier moves with a speed of 64 nm/s. How many years would it take for the glacier to move 0.8 km? Assume there are

365 days in a year.

time = (distance)/(speed)

= (800 m)/(64*10^-9 m/s)
= 1.25*10^10 s
= _____ years
Do the conversion

To answer this question, we need to convert the units and then calculate the time it would take for the glacier to move 0.8 km.

First, let's convert the given speed from nanometers per second (nm/s) to kilometers per year.

1 kilometer (km) is equal to 1,000,000,000 (1 billion) nanometers (nm).

To convert nm/s to km/year, use the following conversion factors:
1 km = 1,000,000,000 nm (1 billion nm)
1 year = 365 days

So, the conversion can be done in two steps:
Step 1: Convert nm/s to km/s
Step 2: Convert km/s to km/year by multiplying it by the number of seconds in a year.

Step 1:
Since 1 km = 1,000,000,000 nm,
64 nm/s * (1 km / 1,000,000,000 nm) = 6.4 * 10^(-8) km/s

Step 2:
To find km/year, we multiply km/s by the number of seconds in a year:
(6.4 * 10^(-8) km/s) * (60 seconds/minute) * (60 minutes/hour) * (24 hours/day) * (365 days/year) ≈ 2.02 km/year

Now that we have the speed of the glacier in km/year, we can calculate the time it would take for the glacier to move 0.8 km.

0.8 km / 2.02 km/year ≈ 0.396 years

Therefore, it would take approximately 0.396 years for the glacier to move 0.8 km.
