Answer:
The speed of the rain is  [tex]v_R = 95.3 km/hr[/tex]
Explanation:
From the question we are told that
 The initial speed and direction of the car is  [tex]v = 55 \ k/hr\[/tex]
  The angle made with the horizontal is  [tex]\theta = 60^o[/tex]
  The velocity of rain is  [tex]v_R[/tex]
An  illustrate  of this question is shown on the first uploaded image
  From the diagram we see that
        [tex]tan \theta = \frac{v_R}{v }[/tex]
=> Â Â Â Â Â Â Â [tex]v_R = v * tan \theta[/tex]
substituting values
          [tex]v_R = 55 * tan (60)[/tex]
         [tex]v_R = 95.3 km/hr[/tex]
