Please see the explanation

#### Explanation:

Assume the projectile is launched with a speed

**Time of Flight**:

**Range of the projectile**:

**Height of the projectile**:

Given that :

Now substitute the numerical values of

When the projectile is at maximum height, its coordinates are

So its distance from the origin is ;

From the numerical values of
