Phobus is a potato shaped body measuring 27x22x19 km having a mass of 10^16 kg. The shape of the satellite has nothing to do with the radius of Mars or its distance from Mars. Perhaps you are seeking something else.

i ended up finding the answer after i posted it on this site.

i wrote out9350/3400=31/x

it came to 11.27 (which is the correct answer according to the scoring key that is used)

Thank you for your help though!!! :lol:

Exactly what were you seeking>

What is the significance of 9350/3400 = 31/x?

What does the 31 represent?

From point X to point P the measure = 31
Somehow the answer came out correct....

Thank you for ur help
