A train of proper length 750m750m approaches a platform of length 1110m1110m at 0.750.75 times the speed of light from the left.

Observers on the platform measure the time interval in which the train overlaps with the platform. (The time it takes for the front of the train to reach the left end until the time when the rear of the train passes the right end of the platform). For each calculation you do, state which reference frame has the proper measurement and explain why.

Use c=2.99×108m/sc=2.99×108m/s.
