1 [4] Measures – speed, distance, time, area, volume,
-Minimum width is 45m Maximum width is double minimum width Football (rectangular) pitch dimension rules: Jane says ‘the maximum area of a pitch is at least 50% greater than the minimum -Maximum length is 120m -Minimum length is ¾ of maximum length area.’ Is she correct? Justify your answer. A large carton contains 4 litres (4000 cm3) of orange juice. Cylindrical glasses of height 10 cm and radius 3 cm are to be filled from the carton. How many glasses can be filled? The weight of a 2p coin is 7g. Find the weight of £10 worth of 2p coins. Give your answer in kilograms. She uses the rule ‘Cook for 40 minutes per kg and then add 25 minutes.’ A chef needs to cook a 4.5 kg turkey, to be ready for 1:30pm. What is the latest time she should begin cooking the turkey? A cardboard box, in the shape of a cuboid measures 45cm by 26cm by 23cm. Small wooden blocks are cubes of length 5 cm. What is the maximum number of blocks that can be packed in the cardboard box? Anne travelled 200 miles by car from Preston to Bristol. Her car clock showed 13:25 at the start of her journey. She stopped at the services at 3:40pm. At 4.05pm, she continued on her journey. When she arrived at Bristol her car clock showed 17:50. What was her average speed whilst driving? Dylan uses the formula miles per gallon = miles travelled x ÷ litres of fuel used One weekend, Dylan travelled by car from Holyhead to Swindon. He then went to Cardiff before returning to Holyhead. The distance travelled: Holyhead to Swindon was 256 miles; Swindon to Cardiff was 88 miles; Cardiff to Holyhead 227 miles. He used a total of 62 litres of fuel. Calculate the mpg for his car to the nearest whole number. A gold bar, in the shape of a cuboid, measuring 20cm by 8cm by 4.5cm is melted down to make small cubes of sides 2cm. How many small cubes can be made from the gold bar? A rectangular tank has a length of 20cm, width of 15cm and height of 10cm. Water is poured into the tank until it is half full. Calculate the volume of water in litres (1000cm3 = 1 litre). Measures – speed, distance, time, area, volume, The speed limit through some roadworks is 50mph. Cameras recorded the time taken for a car to travel 600m through the roadworks as 27 seconds. 10 mph is approximately 4.47 m/s Was the car speeding through the roadworks? Nicola drove from her home to her friend’s house. It took her two and a half hours, driving at an average speed of 30mph. Her return journey, along the same route, took three hours. Calculate her average speed home. During April, Laura drove a total of 560 miles in her car. Her car’s fuel consumption was 37.8 mpg. Petrol cost £1.48 per litre. 1 gallon = 4.55 litres. Calculate the cost of petrol she used.
