Question

If you are traveling at 8 knots for 45 minutes, how far will you have traveled in nautical miles?

Answer 1

6 nautical miles

Explanation:

General equation: `"Rate" = "Distance"/"Time"` or (`R = D/T`)
R = 8 knots = 8 nautical miles/hour
D = x nautical miles
T = 45 minutes = 0.75 hours

So:
#8 "knots" = x /(0.75 "hours") #

`8 "knots"*0.75 "hours" = x`

#x = 6 "nautical miles" #

PS:
A car going x mph will travel x miles in 1 hour
Similarly, a ship going x knots will travel x nautical miles in 1 hour
