Answer 1

Answer:

almost 18sec(d)

Step-by-step explanation:

the trains have to cross (350+250)m=600m

each second they cross [{(18+108)×1000}/3600] m together. =35m

so, they take (600÷35)=17.14....sec

Answer 2

Answer:

24SEC

Step-by-step explanation:

T=D/S       , S=108KMPH-18KMPH=90KMPH=90*5/18=25M/S

=600/25

=24 SEC
