Two masses, m1= 3.0 kg and m2 = 4.0 kg rest on a frictionless surface as shown. A force of 7.0 N is applied to m1. What is the acceleration of the two masses?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
