Question

A railway passenger counts the telegraph posts on the line as he passes them while travelling. If the poles are $50$ m apart and the train is going at the speed of $48$ km/hr How many posts will be passed by the train per minute ?

• A. $16$
• B. $17$
• C. $18$
• D. $20$

Answer 1

$\therefore$ Number of Telegraph posts passed $=800÷50=16$
