Answer:
0.07 litres/minute
Explanation:
Given the amount of water in millilitres to be 10 ml
Time taken for the water to flow = 8.5 seconds
Rate of flow in ml/sec = amount of water (in ml)/Time taken(in secs)
Rate of flow in ml/sec = 10ml/8.5scs
To express the resulting value in litres per minute, we will use the following conversion:
1 millilitre = 10⁻³litres
60secs = 1 minute
Converting 10ml to litres:
If 1 millilitre = 10⁻³litres
10 millilitres = (10*10⁻³)litres
Converting 8.5secs to minute:
If 60secs = 1 minute
8.5secs = (8.5/60)minutes
8.5secs = 0.1417 minutes
10ml/8.5scs in litre/sec:
10ml/8.5scs = (10*10⁻³)litres/0.1417 minutes
10ml/8.5scs = (0.01/0.147)litres/min
10ml/8.5scs = 0.07litres/minute (to the nearest hundredth)
Hence the rate of flow in liters per minute to the nearest hundredth is 0.07litres per minute.
