daily riddle #21
You are doing a bycicle tour. Your goal is to complete a 20km track in 40min. After half way you realize that you have driven an average speed of 20km / h. How fast do you have to travel the rest of the way to reach your goal?

If you are travelling 20kms an hour then you have travelled 10km in 30 minutes. That leaves 10 minutes to travel another 10 km
10 minutes x 6 is 1 hour
10km x 6 is 60kms an hour
I agree
