use suvat in the horizontal direction
We understand you want to help but forum guidelines ask that you do not post the complete solution to a question.
Give a hint as to how to do it.
Secondly, you do not need to use a suvat for the horizontal component of motion as it is uniform velocity.
v = s/t is sufficient.

use suvat in the horizontal direction (s=ut+0.5at^2)
so s=58, t=2.7 and a=0
58=2.7u+0.5x0x2.7^2
u=58/2.7=21.48m/s
as a=0, velocity stays at 21.48 m/s
so s=58, t=2.7 and a=0
58=2.7u+0.5x0x2.7^2
u=58/2.7=21.48m/s
as a=0, velocity stays at 21.48 m/s
I get confused with the initital and acceleration for vertical and horizontal Could you explain?

Stonebridge could you explain horizontal and vertical(projectiles) like the acceleration and initial speed i keep getting confused

If your doing M1, pretty much all you need to know for projectile motion is the acceleration in the vertical direction is (I think always) g which is 9.8ms^-2 towards the ground and acceleration in the horizontal direction is 0. So horizontal velocity doesn't change but vertical velocity does (so you need suvat for those questions).
