Data Handling Speed/Distance/Time
Data Handling D Distance S T Speed/Distance/Time Speed Time
Data Handling We can calculate the distance something travels by multiplying it’s speed by the time it travels: Speed x Time = Distance Speed/Distance/Time
Data Handling If a car is driven at 60mph for 1 hour it will cover a distance of 60 miles If the car is driven at 60mph for 2 hours it will cover a distance of 60 miles each hour for 2 hours (2 x 60miles = 120 miles) Speed/Distance/Time
Data Handling Sometimes we know how far the car has travelled in an hour but not the speed it travelled at. Speed/Distance/Time The car travelled 120 miles in 2 hours 120 miles divided by 2 hours = 60mph
Data Handling Finally we sometimes know the distance travelled and the speed but do not know how long it takes: Speed/Distance/Time The car travelled 120 miles at 60mph 120 miles divided by 60mph = 2 hours
Data Handling It can be quite difficult to remember what we do, multiply by time? Divide by distance? Speed/Distance/Time We can use a clever technique call the magic triangle. All we need to remember is: Distance = Speed x Time
Data Handling D Distance S x T Speed/Distance/Time Speed Time We cover over the thing we do NOT know
Data Handling D Distance S x T Speed/Distance/Time Speed Time If we don’t know the Speed… …the triangle tells us it is Distance over Time
Data Handling D Distance S x T Speed/Distance/Time Speed Time If we don’t know the Distance… …the triangle tells us it is Speed x Time
Data Handling D Distance S x T Speed/Distance/Time Speed Time If we don’t know the Time… …the triangle tells us it is Distance over Speed
