The table shows the time taken by some men to complete the night marathon. Mark completed the race in
23 of the time taken by Ethan. If David reached the finishing line at 01 25, what time did Mark cross the finishing line? Leave your answer in 24-hour clock.
Name |
Time taken |
David |
256 h |
Ethan |
243 min |
Mark |
? |
3 u = 243
1 u = 243 ÷ 3 = 81
Time taken by Mark
= 2 u
= 2 x 81
= 162 min
1 h = 60 min
Time taken by David
= 2
56x 60
= 170 min
Difference in time
= 170 - 162
= 8 min
8 min before 01 25 = 01 17
Time that Mark crossed the finishing line = 01 17
Answer(s): 01 17
