does any one know how to answer this problem?
A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000 km. Suppose it accelerates at an acceleration 20.6 for the first time interval 16.0 of the trip, then travels at constant speed until the last time interval 16.0 , when it accelerates at 20.6 , just coming to rest as it reaches the moon.

What is the maximum speed attained?

What fraction of the total distance is traveled at constant speed?

What total time is required for the trip?

Not the way it is worded. Please don't confuse the OP. It looks to be a straightforward kinematics question.
