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

Riordan |

2 u = 252
1 u = 252 ÷ 2 = 126
Time taken by Riordan
= 1 u
= 1 x 126
= 126 min
1 h = 60 min
Time taken by Ahmad
= 2
25x 60
= 144 min
Difference in time
= 144 - 126
= 18 min
18 min before 03 40 = 03 22
Time that Riordan crossed the finishing line = 03 22
Answer(s): 03 22
