Respuesta :
54/9 = 6
12 x 6 = 72
72 feet in 54 seconds
54/72 = 0.75
1 foot = 0.75 seconds
0.75 x 54 = 40.2 seconds to travel 54 feet
12 x 6 = 72
72 feet in 54 seconds
54/72 = 0.75
1 foot = 0.75 seconds
0.75 x 54 = 40.2 seconds to travel 54 feet
Answer:
40.5 sec
Step-by-step explanation:
The flow rate is (12 ft) / (9 sec), or 4/3 ft/ sec.
In 54 sec, the water will have moved
(4/3 ft/sec)(54 sec) = 72 ft.
If the flow rate is 4/3 ft/sec and the distance covered is 54 ft, we divide
54 ft by (4/3 ft/sec) to determine how long it takes the water to flow 54 ft:
54 ft
---------------- = 40.5 sec
(4/3 ft/sec)
