A person jogs 4.0 km in 32 minutes, then 2.0 km in 22 minutes, and finally 1.0 km in 16 minutes. What is the jogger’s average speed in km per minute?
What is 0.09 km / minute?
(4 km / 32 min = 0.125 km/min)
(2 km / 22 min = 0.09 km/min)
(1 km / 16 min = 0.06 km/min )
LAST STEP: (0.125 + 0.09 + 0.06 / 3 = 0.09 km / min)
