IB Sample Exam Q10, Paper 1

This video is the last video for paper 1 of the Sample IB exam.
In this video, you have to derive a formula to show the amount of time a farmer takes to cross a field and reach another point. After finding the formula, you then have to find where he should travel to along a road in order to minimize his time. You must justify this using calculus.

Wow this video just popped up to me and I still remember that I learnt math through your channel and graduated as an engineer 4 years ago . The only difference now and then is that you are now using an iPad lol .. in my times it was real papers and pen. Well done sir

Your videos have helped me endlessly, 7 years later I am still back at this channel remembering how many times I have viewed your videos and how much help they've provided. Thank you for sharing your knowledge with us

But why did the farmer cross the field. Was he happy with his life? These are most important questions.
