Explanation of Solution
Given information:
At lunchtime, M cast a shadow 0.5 ft long while a nearby flagpole cast a shadow 2.5 ft long. M is 5 ft 3 in tall.
Given options are,
F. 26 ft 3 in
G. 26 ft 4 in
H. 26 ft 5 in
I. 26 ft 6 in
Calculation:
M cast a shadow 0.5 ft long while a nearby flagpole cast a shadow 2.5 ft long.
Clearly the height of shadow of the flagpole is 5 times the height of the shadow of M.
So, the height of the flagpole is 5 times the height of M.
The height of the flagpole is obtained as follows.
The correct answer is F.
