06 April 2011

on question 6 in level up maths 4-6

06 April 2011

can you post a link to that question or write it on here? What is it asking you to do?

06 April 2011

On a boat-handling course, kim was given three instruction

06 April 2011

ok so start off by drawing a North line

06 April 2011

Q1: Make a scale drawing (1cm=100m)

06 April 2011

Go 1500m on a bearing of 120degrees, then travel north for 00m

06 April 2011

Q2:In a straight line, how far is kim from her starting point

06 April 2011

then find 120 degrees with a protractor and draw a line to this point

06 April 2011

from where?

06 April 2011

from the middle of the line

06 April 2011

?

06 April 2011

no, from the bottom of your North line

06 April 2011

ok next?

06 April 2011

the length of the line needs to be the distance she's travelling in km, but converted into cm

06 April 2011

1500m

06 April 2011

ok so there are 100m in a km so it's going to be 1.5 km

06 April 2011

wqould that be 5cm?

06 April 2011

sorry your scale is 100m = 1cm right?

06 April 2011

so shall i draw a line of 1.5cm?

06 April 2011

yep

06 April 2011

10cm=1cm

06 April 2011

so it's going to be 15cm long

06 April 2011

1500/100 = 15

06 April 2011

is that it?

06 April 2011

then when you get to that end point, draw a straight line to the starting point

06 April 2011

exactly

06 April 2011

ok so from this point all you have to do is draw a line North of 5 cm

06 April 2011

will that be a straigt line for 5cm?

06 April 2011

then travel north for 500m

06 April 2011

so from the north line to the bottom

06 April 2011

from the line you've just drawn, to her start point

06 April 2011

then measure that length in cm and convert it back to km

06 April 2011

q2: In a staright line , how far is kim from her starting point?

06 April 2011

will that be 20cm cauz 15+5=20cm,

06 April 2011

1 min

06 April 2011

ill be back

06 April 2011

no it's not 15 + 5 because you would have travelled 15cm on a bearing of 120 degrees and then an extra 5cm due north

06 April 2011

so you're going to end up with a sort of triangle that you have to measure one side of

06 April 2011

have a look at this page to see what I mean http://www.mathsrevision.net/gcse/pages.php?page=12

06 April 2011
