Question

two train of length 300 m and 250 m are moving. each train has speed of 85 km/h and moving in the opposite direction. how long will it take them to pass each other​

Answer 1

Answer:

The total length of two trains =300+250 =550 m

combined speed of two trains =85+85 =170 kmph.

Time taken by two trains to cross each other =550m /170 kmph =550 /[(170 ×1000)/3600]

=550 × 3600/(170×1000)

= 11.65 seconds

Time taken to the trains to pass each other is 11.65 seconds .

Answer 2

Answer:

11.65 seconds

Step-by-step explanation:

length of trains are  300 and 250m if we add them we get 550m

both trains speed is 85km/hr

so, both trains speed will be 170 kilometre per hour (85+85)

for them to pass will be 550 divide by 170 (550/170) = 550m /170 kilometre per hour =550 / [(170 ×1000)/3600]

=550 × 3600/(170×1000)

if we total it we get 11.65 seconds
