Answer: They were 3000 feet far apart in 5 minute

Step-by-step explanation:

After leaving school, Alice walked at an average speed of 280 ft/min.

Distance = speed * time

Distance covered by Alice after 5 minutes is

280 * 5 = 1400 feet

Dave walked at an average speed of 320 ft/min. Distance covered by Dave after 5 minutes is

320 * 5 = 1600 feet

Total distance covered by Alice and Dave after 5 minutes is

1400 + 1600 = 3000 feet

they were 3,000ft apart in 5 minutes.

Step-by-step explanation:

280x5=1,400

320x5=1,600

1,400+1,600=3,000
