Answer:
t = 1.0 hours
Explanation:
as we know that all the data is given here in 2 significant figures
so here we need to find the total time of the motion
that time must be in two significant figures
here we know that
[tex]t_1 = 25 min[/tex]
[tex]t_2 = 35 min[/tex]
so here total time is given as
[tex]t = t_1 + t_2[/tex]
[tex]t = 25 + 35 [/tex]
[tex]t = 60 min[/tex]
[tex]t = 1.0 hour[/tex]
