Find a formula for a function describing the given situation. Graph the function and give a domain that makes sense for the problem. Recall that with constant speed, distance$=$speed$\cdot$time elapsed or $d=v t.$

A function $y=f(x)$ such that if you ride a bike for 50 mi at $x$ miles per hour, you arrive at your destination in $y$ hours

$$f(x)=y=\frac{50}{x}$$

so recall that with a constant speed, distance is going to be able to velocity times time. So if our distance is 50 miles and our velocities X and then our time is why then he saw for why why is going to be 50 over x?
