1. 18x-2
5.403 is bigger than 5.03 bc it has a 4 in the tenths place
The first thing you should know for this problem is the definition of speed.Speed is defined as the quotient between distance and time.
v = d / t.
Substituting the values, we have:
v = (100 + 400) / (30) = 16.67 m / s
answer
the train going at 16.67 m / s
Answer:
