Answer 1

Answer:i know the answer now yesterday my friends told me the answer.The answer is

Step-by-step explanation:when you divide 990 by 55, you will get

18 m per sec

1 min=60sec

so 18 times 60=1080m per min

1 hour=60 min

so 1080 times 60=70800m per hour

then 1000m = 1 km

so 70800m devided by 1000= 70.8km per hour

so the answer is the speed of the train is 70.8 km per hour
