Physics problem helpp

    Physics problem helpp!!

    1. A projectile is launched at a angle and it lands on the same horizontal plane. The range of this launch is 23m. The projectile is launched again at the same angle with triple the speed. What is the new range?

    2. x=v0t <---- I know that finding the time would be useful, but i am not sure if this is the right equation to solve for time.

    3. I know that x= 23m but i have no idea how to find the new range. After I find out what the time is I would triple it and plug it into the equation x= v0t+1/2at^2. I'm not sure if this is right!!
    Thank You if you can help me.
