The Answer is F.
20min - 30min is -10 so you can take it out of 8h which will leave you with 7h and 50 minutes then
7h and 50 min minus 10 h is -3 h and 50 minutes take it out of the 7 day’s which leaves you with 6days and 24 h minus 3 h that it 6days and 21 h and 50 minutes in total and minus the ram aiming 4 days which will be
2days 21 hours 50 minutes and that gives you the answer F
1km = 1000m
1hr = 3600sec
Do proportions:
1km / 1000m = 15km / x
15000m = x
1hr = 3600sec
15000/3600 = 4.2m per second
