Question: An industrial loom weaves 15 centimetres of cloth every second. Approximately, how many seconds will it take for the loom to weave 45 metres of cloth?

Solution:
in one second the loom waves = 15 centimetres = 0.15 metres

so, the time to loom 45 metres is = (45/0.15) seconds
= 300 seconds
= 300/60 minutes
= 5 minutes
