Question

Traveling on the express train from New York to Baltimore takes approximately 2 hours and 45 minutes. The local train travels the same route from New York to Baltimore and takes approximately 3 hours and 40 minutes. Rounding to the nearest tenth, how many times as long is the journey time of the local train as the journey time of the express train?

Answer 1

The local train's journey time is 1.3 times as long as the journey time of the express train.

Explanation:

Given that:

Travelling time of express train = 2 hours and 45 minutes

We will convert this time into minutes

Travelling time of express train = 2*60 + 45 = 120+45 = 165 minutes

Travelling time of local train = 3 hours and 40 minutes = 220 minutes

Let,

n be the number of times.

Local train travelling time = Number of times * Express train travelling time

220 = n * 165

Dividing both sides by 165

`(220)/(165)=(165n)/(165)\\1.3 = n`

Hence,

The local train's journey time is 1.3 times as long as the journey time of the express train.
