The table shows the distance Mr Goh jogged each day over a period of 4 days. The distance Mr Goh jogged follows a pattern. Based on the pattern, what is the distance Mr Goh jogged on Day 9?
Day |
1 |
2 |
3 |
4 |
Distance jogged |
200 m |
325 m |
450 m |
575 m |
Pattern for the distance jogged:
Day 1: 200 + 0 x 125 = 200 m
Day 2: 200 + 1 x 125 = 325 m
Day 3: 200 + 2 x 125 = 450 m
Day 4: 200 + 3 x 125 = 575 m
Formula:
Distance jogged = 400 + (Day number - 1) x 125
Distance jogged on Day 9
= 200 + (9 - 1) x 125
= 200 + 8 x 125
= 1200 m
Answer(s): 1200 m
