The table shows the time taken by some men to complete the night marathon. David completed the race in

Time taken |
Andy |
256 h |
Ken |
210 min |
David |

5 u = 210
1 u = 210 ÷ 5 = 42
Time taken by David
= 4 u
= 4 x 42
= 168 min
1 h = 60 min
Time taken by Andy
= 2
56x 60
= 170 min
Difference in time
= 170 - 168
= 2 min
2 min before 03 20 = 03 18
Time that David crossed the finishing line = 03 18
Answer(s): 03 18
