A spaceship ferrying workers to moon Base i takes a straight-line

A spaceship ferrying workers to moon Base i takes a straight-line pat from the earth to the moon, a distance of 384,000km, Suppose the spaceship starts from rest and accelerates at 20.0 meter per second squared (m/s2).for the first 15.0min of the trip, and then travels at constant speed until the last 15.0 min, when it slows down at a rate of 20.0 meter per second squared (m/s2),. Just coming to rest as it reaches the moon, (a) what is the maximum speed attained?? (b) what fraction of the total distance is traveled at constant speed?? (c) what total time is required for the trip???
