  1. Tuesday, 04 November 2014 TimeSpeed and Distance These quantities and found by using these formulae (rules): Distance = Time X Speed Speed= Distance ÷Time Time= Distance ÷ Speed

  2. D Distance = Speed X Time Speed= Distance ÷Time Time= Distance ÷ Speed S T x • A car travels at 30 mph for 2 hours. How far has it travelled? • D = S x T D = 30 X 2  D = 60 miles • A cyclist travels 45 miles in 3 hours. What is the cyclist’s speed? • S = D ÷ T S = 45 ÷ 3  S = 15 mph • A plane covers a distance of 1200 miles at a speed of 300 mph. How long will it take to complete this journey? • T = D ÷ S T = 1200 ÷ 300  T = 4 hours

  3. If the time is in hours and minutes, change it to hours and decimal parts of a hour like this: 2 hours 24 minutes = 2. 4 24 ÷ 60 = 0.4
