bogdanovich [222]

Answer:

speed is 81.03 mph

direction is N 3.58 W

Explanation:

given data

travel north = 70 mph

Stream current = 12 mph

direction = S 25° E

result due north = 70 mph

to find out

speed and direction

solution

we will get component of resultant  that is

v cosθ  and v sinθ

so

( 12cos295 , 12 sin295 )    at ( 0, 70)

as that we can say

v sinθ + 12sin295 = 70      ....................1

v cosθ + 12 cos295  = 0     ......................2

so

vcosθ  = -5.0714

vsinθ = 80.8756

now by ratio

cosθ /sinθ  = -5.0714/ 80.8756

cot θ = -0.0627

θ = 93.58

so direction is N 3.58 W

and

we know

vcosθ  = - 12cos295

v = - 12cos295 / cos(93.58)

v = 81.03 mph

so speed is 81.03 mph
