The longer an object, the longer the shadow they cast at a given time of the day and vice versa. This is called direct proportionality. At the same time,
If 15 foot flagpole ---- casts 11 foot shandow

The proportion would therefore be:
Length of shadow cast by tree = (28/15)*11 = 20.533 foot.
Answer:
0.51km × 1000 = 510m
510m × (3×7) = 510m × 21 = 10710m in whole

then we count how much days are in three weeks ( 3 weeks × 7 days)
then we just multiply the meters per day × the days
99% it's true
