Let's show how I learn math...

Andreas has 4 km til school. How many minutes does it take for him to come to school if he ride by bike in 16km/h?

4 km to school
16 km/h
How long time to bicykle to school?

4 km = 4000 m
16/4000=0,004
0,004 * 16 = 0,064
0,064 * 40000= 256
256/16=16
16/16=1
256/4=64 (256 av 4,000=4)
1/64= 0,015625

Answer: 15 minutes or 0 days 0 hours 15 minutes 6 seconds and 25 microseconds...
