\u00a0WEEK FIVE
\n<\/strong>CALCULATION OF DISTANCES AND LOCAL TIME
\n<\/strong>Calculation of distance using lines of latitude
\n<\/strong>Procedures:
\n<\/strong><\/p>\n

    \n
  1. locate the two places involved\n<\/li>\n
  2. find the latitude difference between the two places\n<\/li>\n<\/ol>\n

    Note: \u00a0\u00a0\u00a0\u00a0North-North= subtract
    \n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0North-South= add
    \n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0South-North= add
    \n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Equator-North= add or subtract
    \n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Equator-South= add or subtract<\/p>\n

      \n
    1. multiply the latitude difference by 111km\n<\/li>\n<\/ol>\n

      \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a01\u00b0=111km( 1\u00b0 of latitude is approx. 111km on land) <\/p>\n

      \u00a0Example 1
      \nCalculate the distance between S.Africa(30oS) and Spain(40oN)
      \nSolution:
      \ni) Lat.diff.=30oS+40N=70o
      \nsince 1o=111km
      \ntherefore, 111\u00d770=7770km
      \nThe distance b\/w S.Africa and Spain=7,7770km<\/p>\n

      \u00a0EVALUATION QUESTIONS
      \n<\/strong><\/p>\n

        \n
      1. What is the distance between place A (lat.20oS) and place B (lat.51oN)?\n<\/li>\n
      2. What is the distance between the Equator and Lagos (14oN)?\n<\/li>\n<\/ol>\n

        \u00a0Calculation of Local Time using the lines of longitude<\/strong>
        \n\t\tProcedures:
        \n<\/strong><\/p>\n

          \n
        1. locate the places involved\n<\/li>\n
        2. find longitude difference\n<\/li>\n
        3. conversion to time\n<\/li>\n
        4. adjust time according to the direction of movement(west or east)\n<\/li>\n<\/ol>\n

          \u00a0Examples:
          \n1. If the time at town A(long.75\u00b0W) is 5.00pm on Friday, what will be the time and day at town B(long.120\u00b0E) ?
          \nSolution:
          \ni) Long.diff.=75\u00b0+120\u00b0=195\u00b0
          \nii) conversion to time=195 (since 15\u00b0=1hr)=13hrs
          \n \u00a0\u00a0\u00a0\u00a0 15<\/p>\n

          \u00a0iii) adjustment of time according to direction of movt.=5pm+13hrs(add,since it is due east)=6.00am on Saturday<\/p>\n

          \u00a0EVALUATION QUESTION
          \n<\/strong>Explain how to use longitude to calculate local time<\/p>\n

          \u00a0GENERAL EVALUATION
          \n<\/strong>When it is 2.00pm at GMT; what is the time in <\/p>\n

            \n
          1. Ethiopia (45oE)?\n<\/li>\n
          2. Los-Angeles (75oW)?\n<\/li>\n
          3. Nigeria (15oE)?\n<\/li>\n<\/ol>\n
