3 seconds
Explanation
we have a graph where
x-axis: indicates the time
y-axis:indicates the height
to solve this we need to find the time, where the maximum heigth is reached
Step 1
check the coordinate where the maximum heigth is reached
and go down vertically to intersect the x-axis:
so, we have , it took around 3 seconds to reach the maximum heigth
I hope this helps you
