Laura paddles in her canoe at a speed of 5 mph for 5 miles.

As we know that

$\text{Distance=Speed*Time}\\ \\ Time=\frac{Distance}{Speed} \\$

Substitute the values we get

$Time=\frac{5m}{5mph}=1hr.......(i)\\$

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.

Again using the above formula we can write

$Time=\frac{12m}{6mph}=2hr.......(ii)\\$

Hence from equation (i) and (ii), we can say total time of travel $=1hr+2hr=3hr\\$
