a person 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? ple
ase make sure to explain.
1 answer:
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
