The rate at which the arrow is fired in km/min 40 km/min
Step-by-step explanation:
Step 1:
Convert the miles in to km.
We have 1 mile = 1.6 km
So 150 mph = 150*1.6 km/hr = 240 km/hr.
Step 2 :
Convert the hours into minutes.
We have 1 hour = 60 mins
So in one hour the arrow travels 240 km, therefore in 1 min it will take 240/60 mins
The rate at which the arrow is fired in km/min is 240/60 = 40 km/min
You divide both sides by -16 so you get
X>4
