a 550 m long tunnel?​

Answer 1

Answer:

Step-by-step explanation:

350+550=900 total distance

speed of train= 108 km/hr

Time=distance/speed=900/108=8.333...

Answer 2

Step-by-step explanation:

Distance= 350m+550m

= 900m = 0.9km

speed= 108km/hr

Time= 0.9km/108km/hr= (1/120)×60×60sec = 30 sec.
