Expert Answer:

begin mathsize 16px style T i m e equals fraction numerator D i s tan c e over denominator S p e e d end fraction equals fraction numerator 600 over denominator 60 space end fraction equals 10 space h o u r s
W h i l e space c o v e r i n g space a space d i s tan c e space o f space 600 space k m comma space a space c a r space w i l l space s t o p space f o r space h a l f space a n space h o u r space a f t e r space e v e r y space 100 space k m.
rightwards double arrow T h e space c a r space w i l l space s t o p space f o r space 5 space m i n u t e s
i. e. space a f t e r space 100 space k m comma
a f t e r space 200 space k m comma
a f t e r space 300 space k m
a f t e r space 400 space k m
a f t e r space 500 space k m
S o space s t o p p a g e space t i m e space equals space 5 space cross times space h a l f space a n space h o u r space equals space 5 space cross times space 0.5 space equals space 2.5 space h o u r s
S o space t o t a l space t i m e space equals space 10 space h o u r s space plus space 2.5 space h o u r s space equals space 12.5 space h o u r s end style
