A cricket ball thrown across a field is at heights `h_1 and h_2` from the point of projection at times `t_1 and t_2` respectively after the throw. The ball is caught by a fielder at the same height as that of projection. The time of flight of the ball in this journey is

A

`(h_1 t_2^2 - h_2 t_1^2)/(h_1 t_2 - h_2 t_1)`

B

`(h_1 t_1^2 + h_2 t_2^2)/(h_1 t_2 - h_2 t_1)`

C

`(h_1 t_2^2 + h_2 t_1^2)/(h_1 t_2 - h_2 t_1)`

D

`(h_1 t_1^2 - h_2 t_2^2)/(h_1 t_2 - h_2 t_1)`
