12. In the diagram AC is parallel to FD and AB = BF 
• p = 64o 
• q = 180o – 110o = 70o 
• <R = <A (AB = FB) 
<r + < A + 64 = 180 
2 r = 180 – 64 
2r = 116 
R = 58o
13. Dave earns $8500 per year. He gets a 4% pay rise.

17. Katya and Leena both live 3 km from school. 
a) Katya walks to school at an average speed of 5 km/h. 
She leaves home at 8 am. 
What time does she get to school? 
t = 3/5 hour =

So, She gets to school at 8.36 am 
b) Leena cycles to school. 
She leaves home at 8: 10 am and reaches school at 
8:30 am. 
What is her average speed? 
8:10 to 8:30 is 20 minutes (1/3 hour) 
So, her speed is 3 km/ 1/3 hour = 9 km/hour
