distance= velocity x time 1 = 450 = 200 m
distance= velocity x time 2 = 43600 = 14400 m= 14.4 km

Explanation:

Data of the problem

velocity= #4 m/s#
time 1= #50 s#

?=how far can she run (= it simply means find the distance)
distance= velocity x time 1 = 4*50 = 200 m

Data of the problem

velocity= #4 m/s#
time 2= #1 h#
?=how far can she run (= it simply means find the distance)
This part is a little tricky, because you need to convert hours to seconds first.

#1 h= 60 min= 60*60 s = 3600s#

distance= velocity x time 2 = 4*3600 = 14400 m= 14.4 km
