tell me please there are two to three questions are in their mock series

Question:
If a man running at 15 kmph crosses a bridge in 5 minutes, length of bridge is:
Options:
A) 1000 m
B) 500 m
C) 750 m
D) 1250 m 
Solution:
T = 5 min = 1/12 hour

Length = S \(\times\) T

= 15 \(\times\) 1/12 = 5/4 km

= 5/4 \(\times\) 1000 m

= 1250 m
