Angle between hands of clock at 10:25 is 147.5 degrees. Trains will collide at midpoint of their initial positions.

• To calculate angle between hands of clock, use formula: |(30*H)-(11/2)*M|

• For 10:25, H=10 and M=25, so angle = |(30*10)-(11/2)*25| = 147.5 degrees

• When two trains are traveling towards each other, their relative speed is added to get the collision speed.

• The collision point is the midpoint of their initial positions along the track.

• For example, if train A starts at ...read more
