Answer:
600 ft in one minute
i don't know if my answer is correct or not
Step-by-step explanation:
Object 1 280 ft/min => 85 m/min => 85/60 m/sec
sim.
Object 2320 ft/min => 98 m/min => 98/60 m/sec
when two bodies move in opp. direction there speeds are added
so
resultant speed is object 1 + object 2
the resultant comes out as 183/60 m/sec
time is given 1 minute
and we know Distance = time * speed
distance = 183/60 * 60 (183/60 is the speed and 60 is the time in sec as 1 min. = 60sec)
so the distance comes out as 183 m
convert it into ft
1m = 3.2 ft
so 600 ft in one minute
Answer: they were 600ft apart after 1 minute.
Step-by-step explanation:
Distance = speed × time
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
280 × 1 = 280 ft
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
