Bill and Amy want to ride their bikes to the school which is 13.9 kilometers away. It takes Amy 45 minutes to arrive at the school and Bill arrives 15 minutes later. How much faster, in meters/second (m/s) is Amy's average speed?

the answer would be   dignified - apex

truck y has a greater velocity than truck x.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
