a. Calculate the length of each leg of the race?
each leg's length
By using distance formula we can find length
I.e. d=
<u>leg 1</u>
PR
=
<u>=21.54</u><u> </u><u>km</u>
<u>leg 2</u>
QR

=<u>16.49 </u><u>km</u>
<u>leg 3</u>
PQ
=
=<u>28.84 </u><u>km</u>
b. Calculate the total racing distance?
<u>The total racing distance</u>=Sum of all side
=PR+QR+PR
=21.54+16.49+28.84
=<u>66.87 </u><u>km</u>
c. If an observer’s boat is located at the midpoint of the second leg of the race, calculate the distance between this boat and the finishing point?
Solution given:
<u>distance between this boat and the finishing point</u>=
=<u>8.25 </u><u>k</u><u>m</u>
