daily riddle #21

in #riddle7 years ago

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?

Sort:  

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
