Noah runs at 7 mph, Ben runs at 5 mph. If they start at the same time,
how long (in minutes) will it be before they are 1/6 mile apart?
:
Convert the speed to ft/min
= 616 ft/min
= 440 ft/min
convert 1/6 mi to ft
*5280 = 880 ft
:
Let t = time in minutes for this to be true
:
N's dist - B's dist = 880 ft
616t - 440t = 880
176t = 880
t =
t = 5 minutes
