## Solution
? = 21⁄25 × 20⁄9 × 5⁄12 ÷ 17⁄10 = 119⁄90 = 129⁄90
## What the question and answer could be
What should come in the place of the question mark(?) in the following equation?
21⁄25 ÷ 9⁄20 × 5⁄12 ÷ 10⁄17
Options:
(A) 7 77⁄125
(B) 11 9⁄10
(C) 119⁄450
(D) 1 29⁄90
(E) None of these
(D)

## Solution
18 m/s = 18 * 18/5 kmph
3 hours 45 minutes = 3 3/4 hours = 15/4 hours
Distance = speed * time = 18 * 18/5 * 15/4 km = 243 km.
