🔍 Key Concepts

• Speed made good is based on the distance directly between the two GPS fixes, not the plotted route or compass corrections from steps 1–3. • Convert the latitude and longitude differences into nautical miles; longitude distance depends on latitude. • Elapsed time from 0856 to 0945 is 49 minutes.

💭 Think About

• What north–south and east–west separations do the two fixes represent, and how can you combine those components to estimate the straight-line distance? • Once you have distance in nautical miles, how do you convert 49 minutes to hours and calculate speed?

✅ Before You Answer

• Use the positions and times stated in this step; steps 1–3 establish other facts but do not provide these fixes. • Check that the final speed is in knots (nautical miles per hour) and compare it with the choices. • Do not apply variation or deviation to GPS positions or this speed calculation.
