pimpchi: (a) Given: Speed for the journey = 380 km Total time taken for the journey = 4hours The journey was in two parts. First part of the journey was on the motorway and the second part was on the country road Let x and y represents the distance and time taken respectively for the journey in the first part (on the motorway); Therefore, the speed on the motorway is calculated as x ÷ y = 110 km/h x = 110y ...... Eqn 1 To get equation 2, let's find the expression for speed on the country road Distance on the country road = 380km - x Time spent on the country road = 4hrs - y Therefore, the speed on the country road = (380 - x) / (4- y) = 70km/h, 380 - x = 70(4 -y), 380 - x = 280 - 70y, 380 - 280 = x - 70y, x - 70y = 100 ....Eqn 2 Therefore, these are the simultaneous equations x = 110y ...Eqn 1 x - 70y = 100 ...Eqn 2 (b) Solving the equations; Sub for x in eqn 2 using eqn 1, x - 70y = 100, 110y - 70y = 100 40y = 100 y = 100/40 = 2.5 hours sub for y in eqn 1, x = 110y, x = 110 (2.5), x = 275km Therefore the distance covered on the motorway is 275km @pimpchi Feel free to ask questions. |

paulolee:No. The planet earth exhibits two motion types at the time. Earth rotates on its polar axis (the earth pole). That one brings day and night. Takes 24hours to make one complete rotation. The second one is the revolution of the earth around the sun. This revolution takes 365¼ days to complete. 1 Like 1 Share |
