@mathslover can u help her

Answer 5

Total distance covered by train will be (length of train + length of platform)
total distance = 400m
speed 90 km/h

Answer 6

iether you change 400 m in km and find time
or the second way is to find speed in m/s then find time

Answer 7

answer will be 16 sec

Answer 8

change km/h in m/sec
\[(90\times 1000 m)\div3600 \sec = 25 m/s\]
time =distance/speed
400/25= 16 sec
