Hi!
Your answer would be:<em> 228ft below the ocean surface.</em>
Reason being: <em>when you subtract 43 from 271, you get 228.</em>
Hope this helps!
If you need anymore help, please let me know!

Answer:
4 V + 4 (V - 60) = D where D is distance apart after 4 hrs
8 V - 240 = 7304
V = 943 km/hr
and V2 = 943 - 60 = 883 km/hr where second plane is 60 km/hr slower
