Aperson jogs 4.0km in 32 min, then 2.0n in 22min and finally 1.0km 16 min. what is the joggers average speed in km per min? make sure to explain.

Speed= distance divided by time so s=d/t

first find the individual speeds during each running segment.  we get

s=4.0/32=1/8 km per min
s=2.0/22=1/11 km per minute
s=1.0/16=1/16 km per minute

now we take the average.  the person jogged a TOTAL of 7.0 km in a TOTAL 70 minutes. so on average, they jogged 7.0/70=1/10 km per minute
