I have just enrolled to a computer sciencee class, and my teacher gave us an assignement about writing a pseudo code, but it's my first time being in computer science class and i don;t have any experience in computer science. Can someone help me?

here is the problem:

You and your friend decided to go to the beach. You have left home one hour earlier than your friend did. Assuming the traffic is normal and you drive 60m/hrs and your friends drives 70m/h. how long will it take your friend to catch up before getting to the beach.

here is the equation

S2*t=s1*(t+h)

s1= your speed

s2= friend speed

h is the hour

if you had to stop for 1/2 hour for food and to put gas in your car. then how long will it take to meet ?

I need to write this in pseudo code
