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.
