The horizontal distance is 
Generally the time taken by the hot magma in air before landing is mathematically represented as

=> 
=>

Then the final velocity of the magma when it hits the ground is mathematically represented s

Here the negative sign mean that the direction of the velocity is towards the negative y -axis
So

=> 
You get a lot of detailed information. hope this helped :)
