Atrain travels 97 kilometers in 4 hours, and then 63 kilometers in 1 hours. what is its average speed? answer? units?

Given data

Train covers a distance

                             (S₁) = 97 Km,    in time (t₁) = 4 hr

and then covers a distance

                              (S₂) = 63 Km,  in time (t₂) = 1 hr

What is the average speed (v) = ?

The average speed of the train is the ratio of the total distance covered to the total time taken,

       since total distance covered = 97 km + 63 km

                                                        = 160 Km

       and total time taken = 4 hr + 1 hr

                                          = 5 hours

       Therefore,

        average speed   = total distance covered /total time taken

                                     = 160 km/ 5 hr

                                     = 32  km/hr

The average speed of the train is 32 km/hr  

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

did yall get answers for this yet
