Inessa05 [86]

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\\

Hi, We know:

Sin(a + b) = 2.Sin(a).Sin(b)

Then,

= 2Sin(a).Cos(b)/Cos(a).Cos(b)

Canceling Cos(b)

= 2Sin(a)/Cos(a)

As Tan(a) = Sin(a)/Cos(a)

Then we will stay:

= 2Tan(a)

Or

= Tan(a) + Tan(a)

There is anything wrong on the alternatives
