A train running at the speed of 90 km/hr crosses a platform of length 160 m in 10 seconds. What is the length of the train (in meters)?
------
Convert 90km/hr to meter per sec.
---
90km/h(1h/3600sec)(1000m/1km) = 25meter/sec
---
Find distance the train travels in 10 seconds.
-------------
= 250 meter/10sec
----
Find length of train:
length + 160 meters = 250 meters
The train = 250-160 = 90 meters long
