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} \\](https://tex.z-dn.net/?f=%20%5Ctext%7BDistance%3DSpeed%2ATime%7D%5C%5C%20%5C%5C%20Time%3D%5Cfrac%7BDistance%7D%7BSpeed%7D%20%5C%5C%20)
Substitute the values we get
![Time=\frac{5m}{5mph}=1hr.......(i)\\](https://tex.z-dn.net/?f=%20Time%3D%5Cfrac%7B5m%7D%7B5mph%7D%3D1hr.......%28i%29%5C%5C%20)
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)\\](https://tex.z-dn.net/?f=%20Time%3D%5Cfrac%7B12m%7D%7B6mph%7D%3D2hr.......%28ii%29%5C%5C%20)
Hence from equation (i) and (ii), we can say total time of travel![=1hr+2hr=3hr\\](https://tex.z-dn.net/?f=%20%3D1hr%2B2hr%3D3hr%5C%5C%20)
