(a) Convert 85 km per hour to metres per second. (b) Convert 10 m per second to kilometres per hour. (c) Convert 61 pence per centimetre into pounds per metre.
These conversion rates will be useful in the following question:
1.609 km 1 mile: 1 kg = 2.2lbs;
60 seconds = 1 minute. 60 minutes equals 1-hour.
So 60 x 60, or 3600 seconds = 1-hour
1000g = 1 kg; 100 cm = 1 m; 100cm x 100cm = 1 m x 1 m, so that 10000 square centir In a similar way 1 cubic metre equals 100 cm x 100cm x 100cm.
1 million square centimetres = 1 cubic metre
or 10° centimetres squared = 1 cubic metre
