Two particle A and B projected along different directions from the same point P on the ground with the same velocity of 70 m/s in the same vertical plane. They hit the ground at the same point Q such that PQ = 480,. Then `[g=9.8 m//s^(2)]`

A

Ratio of their times of flight is `4 : 5`

B

Ratio of their maximum heights is `9 : 16`

C

Ratio of their minimum speeds during flights is `4 : 3`
