Metric Conversions Convert 4 metres to centimetres. 400cm 1.5 kg 30 mm 3.75 litres Convert 4 metres to centimetres. Convert 1500 grams to kilograms. Convert 3 centimetres to millimetres. Convert 3750 millilitres to litres. Shay says 1.5 kilometres is less than 1400 metres. Is she correct? Explain your answer. 1.5km = 1500m, therefore shay is not correct.

Speed, Distance and Time Stuart drives 180 km in 2 hours 15 minutes. Work out Stuart’s average speed. The distance from London to New York is 3456 miles. A plane takes 8 hours to fly from London to New York. Work out the average speed of the plane. John travelled 30km in 1.5 hours. Kamala travelled 42km in 2hours. Who had the greater average speed? 80km/h 432 mph 30 ÷ 1.5 = 20 km/h 42 ÷ 2 = 21 km/h So Kamala had the greater speed.

Speed, Distance and Time 4) There are 40 litres of water in a barrel. The water flows out of the barrel at a rate of 125 millilitres per second. 1 litre = 1000 millilitres Work out the time it takes for the barrel to empty. 40 x 1000 = 40 000 millilitres 40 000 ÷ 125 = 320 seconds or 5 minutes 20 seconds

Density, Mass and Volume The density of juice in 4 grams per cm3. The density of water is 1 gram per cm3. 315cm3 of drink is made by mixing 15cm3 of juice and 300cm3 of water. Work out the density of the drink. 86% of students could not answer this question in the GCSE’s because they could not remember the triangle 1.14 g/cm3

Density, Mass and Volume The volume of a gold bar is 100cm3. The density of gold is 19.3 grams per cm3. Work out the mass of the gold bar. 19.3 x 100 = 1930g or 1.93 kg
