Given :
A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds.
She ends 4 feet up the tree.
Solution :
Now, distance covered is :
d = 4 - 0.5 = 3.5 feet.
Time taken, t = 7.5 seconds.
Distance climbed per second is :
[tex]D =\dfrac{d}{t}\\\\D=\dfrac{3.5}{7.5}\\\\D = 0.467\ feet/s[/tex]
Therefore, distance climber per second is 0.467 feet.
Hence, this is the required solution.
