Alice and Dave left school at the same time walking in opposite directions.

Alice walked at an average speed of 280 ft/min. It means that the distance covered by Alice in 1 minute is

Dave walked at an average speed of 320 ft/min. It means that the distance covered by Dave in 1 minute is

320 × 1 = 320 ft

Total distance covered by both Alice and Dave in 1 minute is

280 + 320 = 600 ft
