well, you know that
F = GMm/d^2
so, d^2 = GMm/F
Now just plug in your numbers.
The gravitational force of attraction between two students sitting at their desks in physics class is 2.34 ✕ 10^-8 N. If one student has a mass of 45.0 kg and the other student has a mass of 61.6 kg, how far apart are the students sitting?

the letter are what again
G is Universal gravitational constant
In these SCI units it is about
6.67 * 10-11 m^3 /(kg s^2)
M is one mass in kg
m is other mass in kg
d is distance between the centers of gravity of the two masses
F is gravitational force in Newtons

hmm this would make the answer
The gravitational force of attraction between two students sitting at their desks in physics class is 2.30 x 10-8 N. If one student has a mass of 45.0 kg and the other has a mass of 55.0 kg, how far apart are the students sitting? Round your answer to the nearest tenth of a meter. Record your answer in the boxes below. Be sure to use the correct place value.
