6. A) 50 metres x a week= 7 days
50 x 7 = 350
B) 350 x 2 = 700
50 x 2= 100 x a week= 7 days= 700.
700 + 700 = 1400 + 350= 1750 metres
3. A) 60 + 60 + 60= 180
180 divided by 20 = 9
9 x 30= 270 metres
B) 60 x 15=900 seconds
900 divided by 20= 45
45 x 30= 1350 metres
C) 60 x 20= 1200 divided by 20= 60
60 x 30=1800 metres
