Answer:
561/4
Step-by-step explanation:
Given that:
Height of first hill (f) = 255 feets
Height of second hill (s) = 11/20 the height of first hill
Height of second hill (s) = 11/20 of 255
Calculate the height of second hill:
s = 11/20 * 255
(11 * 255) / 20
= 2805 / 20
= 561 / 4
Height of second hill = 561/4
