PSLEThe graphs show the total number of leaflets machines G and H printed from the start. Both machines started printing at the same time.
- How many less leaflets did G print than H in 8 minutes?
- Both machines did not change their rates of printing throughout. When G had printed 250 leaflets, how many leaflets had H printed?
(a)
Machine G:
10 min → 50
Machine H:
10 min → 60
Machine G less than Machine H:
10 min → 60 - 50 = 10
1 min → 10 ÷ 10 = 1
8 min → 8 x 1 = 8
Number of leaflets that machine G printed less than Machine H in 8 min = 8
(b)
Machine G:
250 leaflets → 50 min
Machine H:
10 min → 60
1 min → 60 ÷ 10 = 6
50 min → 50 x 6 = 300
Number of leaflets that H had printed when G had printed 250 leaflets = 300
Answer(s): (a) 8; (b) 300
