C-10-Q089mediumsingle_mcq

The two horizontal distances together equal the spacing between the posts—

a $1$ m
b $100$ m
c $1000$ m
d $10000$ m

ব্যাখ্যা

The balloon lies above a point on the line joining the posts, so the two horizontal distances add up to the full spacing. Since $1$ km $= 1000$ m, the sum equals $1000$ m.
