Question

A train 160m long passes a standing man in 18 sec. What is the speed of train?​

Answer 1

Answer:

8  8/9m/s  or    8.89 m/s

Step-by-step explanation:

Since it took the train 18 seconds to travel past the standing man completely, and the train is 160m long, when the end of the train reaches the man, the front of the train would already be 160m away from the man. Since that only took 18 sec, the train travelled 160m in 18 seconds, so its speed is 8  8/9 metres per second,        or 8.89 metres per second.

please mark me as brainliest

thanks
