I want to jump a wire from the positive brake light power wire to another closed circuit to introduce a ground and shut off the primary circuit when the brakes are applied. The primary closed circuit will simulate a 'turbine' spool up, which I wish to interrupt when the brake lights come on while introducting a similar secondary 'turbine' spool down circuit to complete the turbine sound effect of spooling up and down.

Towns A & B are 80 KM apart. A couple arranges to drive from town A & meet a couple driving from town B at the lake, L. The two couples leave simultaneously and drive for 2.50 hrs. in the directions show (the gave me a pic- looks like a triangle). Car 1 has a speed of 90 km/h. If the cars drive simultaneously at the lake, what is the speed of car 2?

how would I find the speed of car 2 if car 1 is 90 km/h.... would I do Vy=gt... but it doesn't make sense...?
