Question

PLEASE HELP!!!

Answer 1

Answer:

The expression is 10t = 65

Step-by-step explanation:

At the point where the local train and the express train meet, both trains would have travelled an equal distance.

A local train leaves the station in Springfield traveling toward New York City at a constant rate of 55 mph.

Let t represent the time it spent in travelling a given distance.

Distance = speed × time

Therefore,

Distance travelled by the local train is 55 × t = 55t

The express train headed for New York City on the same route leaves the station 1 hour later. The rate of the express train is 65 mph. It means that total time spent travelling the same distance as the local train is t - 1

Therefore, distance travelled is

65(t - 1)

Since the distance travelled is the same, therefore,

55t = 65t - 65

65t - 55t = 65

10t = 65
