Homework Help Overview

The discussion revolves around calculating the time it takes for a glacier to move a specified distance of 0.74 km, given its speed in nanometers per second. The problem involves unit conversion and understanding the relationship between speed, distance, and time.

Discussion Character

  • Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for unit conversion from nanometers to kilometers and from seconds to years. There is uncertainty about how to properly perform these conversions and whether the original poster's approach is correct.

Discussion Status

Some participants have pointed out the importance of correcting units and have provided guidance on how to approach the problem. There is an ongoing exploration of the necessary conversions, but no consensus has been reached on the method to solve the problem.

Contextual Notes

Participants note the need to look up the conversion factor for nanometers to kilometers and the number of seconds in a year, indicating that these details are crucial for solving the problem accurately.

a glacier moves with a speed of 41 nm/s. how many years would it take for the glacier to move 0.74 km. answer in units of yr..

ok how do i solve this?

would i multiply 41
.74 and just convert it to yrs?

Have you forgotten where the homework section is already?
 
This is just a matter of correcting the units.

Since the speed is given in nm/s (nanometers per second) but you are given a distance in km and asked for an answer in years.

You will need to know how many nanometers there are in a km. I don't happen to remember what a nanometer is so you will have to look that up (it will probably be given as so many nanometers per meter so you will still need to convert to kilometers.

You will also need to determine how many seconds there are in a year! That shouldn't be difficult: there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365.25 hours in a year.
