speed of car = 95 km/h
speed of truck = 75 km/h
relative speed of car with respect to truck = 95 - 75 = 20 km/h
now we will convert it into m/s
[tex]v_r = 20 * \frac{1000}{3600} = 5.56 m/s[/tex]
now time to cross the truck will be given as
[tex]time = \frac{distance}{speed}[/tex]
[tex]time = \frac{110}{5.56}[/tex]
time = 19.8 s
so it will take 19.8 s to cross the truck
