Nadeen · Answer 1

The entire race took Henry 1hr:36min which is 96min. He has an average speed of 30km/hr means he's been traveling 0.5km/min

30km/hr > 30km/1hr >

30km/60min = 0.5km/min

since Henry took 96min to finish the race we multiply 0.5km/min with 96

0.5km/min*96min=48km

(11+16/60-9-40/60 hr) (30km/hr) = 48km
