Please Tell me step by step how to do it correctly​

Answer 1

Answer:

(B)

Explanation:

11:10 - 9:13

=>2 min (-3 sec)

=>1 min 57 sec

No. of laps is 5000m/400m

=>50/4 =>12.5 laps

So time for one lap is 1 min 57 sec

So time for 12.5 laps is (12.5× 1 min 57 sec)

=>12.5 min + 712.5 sec

Convert 712.5 to min by dividing by 60

=>712.5/60

=>11.875 min

Now we have 11+12 min and (0.5+0.875) min

=>23 min and 1.375 min

=>24 min and 0.375 min

=>24 min and (0.375×60) sec

=>24 min and 22.5 sec
