The speed of the helicopter is 100mile/h with respect to air.

Give v1 a chance to be the speed of the helicopter 

What's more, v2 be the speed of the breeze which has greatness b 

v1 = 100 cos 60o i + 100 sin 60o j 

= 50i + 50√3j 

What's more, from the other idea 

  v2 = an i 

the resultant is given by 

v1 = v1+v2 

=(50+a)i + 50√3j 

As given in the inquiry , the helicopter lands 45* east of north because of the breeze, at that point x part will be equivalent to y segment 

50+a = 50√3 

  a = 50(√3-1) 

 a = 36.6 miles/hr 

Cheers!!
