Can someone help me out with ODE problem in MATLAB! Also if you could kind of explain how to set these up it would be greatly appreciated because I do not understand what to do when given a problem like this and it is super frustrating not being able to solve it.

Car B is 30 miles directly east of Car A and begins moving west at 90 mph. At the same moment car A begins moving north at 60 mph. Both cars are electric prototypes and have a range of only 30 miles. What will be the minimum distance between the cars in miles?

Hint: Let variable x be the distance car A travels in t hours, and variable y the distance car B travels in t hours. Let variable L be the distance between cars A and B after t hours: Write the optimization equation in terms of just one variable, t, with a guess value of t=0.2. Substitute x=60t and y=90t in the equation below Minimize L=[x²+(30-y)²]^(1/2) x and y are non-negative x and y must be less than 30
