Question

Help me please...........

Answer 1

C

Explanation:

We require to find DC

ΔDEC and ΔBAC are similar triangles, hence the ratios of corresponding sides are equal, that is

`(ED)/(AB)` =
`(DC)/(BC)`, that is

`(11.5)/(23.5)` =
`(DC)/(44)` ( cross- multiply )

23.5DC = 506 ( divide both sides by 23.5 )

DC ≈ 21.532

distance travelled = BC + DC = 44 + 21.532 ≈ 65.5 in → C
