Laura paddles in her canoe at a speed of 5 mph for 5 miles.
As we know that
[tex] \text{Distance=Speed*Time}\\
\\
Time=\frac{Distance}{Speed} \\ [/tex]
Substitute the values we get
[tex] Time=\frac{5m}{5mph}=1hr.......(i)\\ [/tex]
Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.
Again using the above formula we can write
[tex] Time=\frac{12m}{6mph}=2hr.......(ii)\\ [/tex]
Hence from equation (i) and (ii), we can say total time of travel[tex] =1hr+2hr=3hr\\ [/tex]
