Answer 2

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

As we know that

Substitute the values we get

`Time=(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=(12m)/(6mph)=2hr.......(ii)\\`

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