#### Question 3

a) i) 31°

W = 180 – 107 – 42 = 31

180° in a straight line

a)ii) Reason is 180 in a straight line so its 180 less 107 less 42 to give the missing angle

b) x = 52°; y= 47°

For x…given JKL & MKN are straight lines, opposite angles in this set up are equal. Hence x = 52

For y….180 – 52 – 81 = 47°

#### Question 15

a) 8.23

b) 1 hour 35 mins

08:45 – 09:00 = 00:15

09:00 – 10:00 = 01:00

10:00 – 10:20 = 00:20

Total time is 0.15 + 1.00 + 0.2 = 1hour 35mins

#### Question 16

a) 20mins

Use HCF & LCM. Work on the normal basis that 3 is 1/3 of 9. So if 9km = 1 hour, 3km = 1/3rd of 1 hour

b) 2km

1/4 of the 8km/h = 15mins. So this is 2km
