Answer:
80 seconds
Explanation:
For this problem, we can use the formula: velocity = distance/time, as we are given two of the unknown values so we can solve for the third.
The variable we are finding is time, so we first need to rearrange the formula to solve for time:
time = distance/velocity
Now we can just plug in our given values and solve:
Velocity = 5m/s
Distance = 400m
t = 400/5
t = 80
It took her 80 seconds to travel that far.
Hope this helped!
