You are on your way to a mining site where you have a very important meeting. The mining site is 300 km away from you and the meeting starts at 11h15. You plan on driving at a speed of 100 km/h, therefore, you leave at 08h00. For the first 100 km you drive your planned speed, but then road construction forces you to slow down to 40 km/h for 40 km. What is the minimum speed you need to drive for the rest of the journey to arrive at the meeting on time
