How to multiply a double array and a double together in java : I'm new to this site, and am working on a school assignment, but got stuck. I was wondering if there is any way to multiply a double []array by a double?

for(int i = 0; i <= speed.length; i++)
    double [] mph = speed[i] * 1.15;

That is my code, but when I compile it in java, it says
 "Incompatible types: double cannot be converted to double[]"


How do I fix this?
