For a science project, I am building a battery operated electric vehicle. Its not a big vehicle just about 3 feet long and about a foot wide. I have got most things covered except one. I need a way to buy/build a switch in the circuitry that cuts off the battery power after a certain time. The aim is to make the car travel a certain distance/time and then stop. What is the best and easy way to build a switch that will operate under these conditions? I have a motor powered by a battery pack and I need this switch in the circuitry so that it can shut power off after a programmed time.

Thanks for taking the time to look at this.
