Answer:
The speed of the plane relative to the ground is 300.79 km/h.
Explanation:
Given that,
Speed of wind = 75.0 km/hr
Speed of plane relative to the air = 310 km/hr
Suppose, determine the speed of the plane relative to the ground
We need to calculate the angle
Using formula of angle

Where, v'=speed of wind
v= speed of plane
Put the value into the formula



We need to calculate the resultant speed
Using formula of resultant speed

Put the value into the formula



Hence, The speed of the plane relative to the ground is 300.79 km/h.
I know you're probably done with this by now, but the answer is *Lake-Effect Snow*

Answer:14 m
Explanation:
Given
Vertical jump make by the dolphin is given by 
Suppose the dolphin jump with an initial velocity of 
so u is given by 
If dolphin launches at an angle
then maximum horizontal range is given by
assuming the of Dolphin to be Projectile so range is given by

substitute the value of 


Range will be maximum for 
thus
