after 2 days of travelling,a group of explorers are 40km east and 50km north of the base camp.a second group are 20km west and 70km south of the base camp.find:
\n" ); document.write( "a)the distance between the two groups, and
\n" ); document.write( "b)a description of the midpoint between the two groups.
\n" ); document.write( "LET BASE CAMP BE O THE ORIGIN.WEST-EAST IS THE X AXIS,SOUTH - NORTH IS Y AXIS
\n" ); document.write( "GROUP ONE IS 40 KM EAST AND 50 KM NORTH .LET THEM BE AT A WITH COORDINATES(40,50)
\n" ); document.write( "GROUP 2 IS 20KM WEST AND 70 KM SOUTH .LET THEM BE AT B WITH COORDINATES(-20,-70)
\n" ); document.write( "AB =DISTANCE BETWEEN 2 GROUPS=SQRT.((40+20)^2+(50+70)^2)=10*SQRT(36+144)
\n" ); document.write( "=10*SQRT(180)=60SQRT(5)
\n" ); document.write( "MIDDLE POINT OF 2 GROUPS IS AT
\n" ); document.write( "MID POINT OF AB =(40-20)/2,(50-70)/2=(10,-10)
\n" ); document.write( "THAT IS 10 KM TO EAST AND 10 KM TO SOUTH. \n" ); document.write( "

\n" );
