Let's denote the speed of the newer personal computer as \(x\) gigahertz. According to the problem, the operating speed of the older personal computer is \(50\) gigahertz, and this is one-fourth the speed of the newer model. Mathematically, we can represent this relationship as: \[\frac{1}{4} \times x = 50\] Now, we solve for \(x\), the speed of the newer personal computer: \[\frac{1}{4} \times x = 50\] To isolate \(x\), we multiply both sides of the equation by \(4\): \[x = 4 \times 50\] \[x = 200\] So, the speed of the newer personal computer is \(200\) gigahertz.
