passing each other means passing the distance of sum of their lengths
i.e. 350 + 420 = 770 meter
together they both cover ,
= 55km/h + 53 km /h
= 55000 meter /3600 seconds + 53000 meter / 3600 seconds
= 550 m / 36 seconds + 530 meter / 36 seconds
= 1080 m / 36 second
= 30 m / s
now ,
1 second --------- 30 meter
?? seconds --------- 770 meter
= 770 / 30
= 25.67 seconds
i.e. 350 + 420 = 770 meter
together they both cover ,
= 55km/h + 53 km /h
= 55000 meter /3600 seconds + 53000 meter / 3600 seconds
= 550 m / 36 seconds + 530 meter / 36 seconds
= 1080 m / 36 second
= 30 m / s
now ,

?? seconds --------- 770 meter
= 770 / 30
= 25.67 seconds
