A glacier moves with a speed of 42 nm/s.
How many years would it take for the
glacier to move 0.78 km?
Answer in units of yr.
To find the time it would take for the glacier to move a distance of 0.78 km, we can use the formula:
Time = Distance / Speed
First, we need to convert the speed from nanometers per second (nm/s) to kilometers per year (km/yr):
1 km = 1,000,000,000 nm
1 year = 31,536,000 seconds
So, the speed of the glacier would be:
42 nm/s * (1 km/1,000,000,000 nm) * (31,536,000 s/1 year) = 1.33 km/yr
Now, we can use the formula with the converted speed:
Time = 0.78 km / 1.33 km/yr = 0.586 yr
Therefore, it would take approximately 0.586 years for the glacier to move a distance of 0.78 km.
