Question

A train 54 km/h speed crosses a 650 m lengthened bridge in 1 minutes. what is the length of the train?​

Answer 1

Answer:

250 m

Step-by-step explanation:

Given:

• Speed = 54 km/h = 54×5/18 = 15m/s
• length of bridge = 650m

Solution:

let length of train be x

Total length crossed = 650 + X

Speed = distance

Time

15 = 650+x

60

15 × 60 = 650+X

900 = 650 + X

x = 900 - 650

x = 250 m
