The table shows the time taken by some men to complete the night marathon. David completed the race in
12 of the time taken by Tommy. If Sam reached the finishing line at 01 45, what time did David cross the finishing line? Leave your answer in 24-hour clock.

Time taken |
Sam |
223 h |
Tommy |
272 min |
David |

2 u = 272
1 u = 272 ÷ 2 = 136
Time taken by David
= 1 u
= 1 x 136
= 136 min
1 h = 60 min
Time taken by Sam
= 2
23x 60
= 160 min
Difference in time
= 160 - 136
= 24 min
24 min before 01 45 = 01 21
Time that David crossed the finishing line = 01 21
Answer(s): 01 21
