The table shows the distance Mr Ng jogged each day over a period of 4 days. The distance Mr Ng jogged follows a pattern. Based on the pattern, what is the distance Mr Ng jogged on Day 12?
Day |
1 |
2 |
3 |
4 |
Distance jogged |
150 m |
225 m |
300 m |
375 m |
Pattern for the distance jogged:
Day 1: 150 + 0 x 75 = 150 m
Day 2: 150 + 1 x 75 = 225 m
Day 3: 150 + 2 x 75 = 300 m
Day 4: 150 + 3 x 75 = 375 m
Formula:
Distance jogged = 400 + (Day number - 1) x 75
Distance jogged on Day 12
= 150 + (12 - 1) x 75
= 150 + 11 x 75
= 975 m
Answer(s): 975 m
