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

Time taken |
Sam |
345 h |
Brandon |
280 min |
Jack |

5 u = 280
1 u = 280 ÷ 5 = 56
Time taken by Jack
= 4 u
= 4 x 56
= 224 min
1 h = 60 min
Time taken by Sam
= 3
45x 60
= 228 min
Difference in time
= 228 - 224
= 4 min
4 min before 02 40 = 02 36
Time that Jack crossed the finishing line = 02 36
Answer(s): 02 36
