**Q :**

A train 270 meters long is running at a speed of 36 km per hour then it will cross a bridge of length 180 meters in :

(A) 40 sec

(B) 45 sec

(C) 50 sec

(D) 35 sec

Correct Answer : B

Explanation :

According to the question the total distance will be (270+180)=450 meter

the speed of train will be in 10 m/sec

so that we knew that D=Speed Χ Time

450=10ΧTime

then Time will be 45 sec
