A train travelled from Oxford to London. The only station it stopped at on
the way was Slough.
At Slough, 56 people got off the train and 134 people got on the train.
There were 318 people on the train when it arrived in London.
How many people were on the train as it left Oxford?
To solve this problem, let's work backwards.
When the train arrived in London, there were 318 people on board. From the information given, we know that 56 people got off the train at Slough and 134 people got on.
So, before the train arrived in Slough, there were 318 - 56 = 262 people on board.
Before people got on at Slough, there were 262 - 134 = 128 people on board.
Therefore, there were 128 people on the train when it left Oxford.
To find the number of people on the train as it left Oxford, we need to subtract the number of people who got off at Slough and add the number of people who got on at Slough.
Number of people on the train at Slough = 318
Number of people who got off at Slough = 56
Number of people who got on at Slough = 134
So, the number of people on the train as it left Oxford can be calculated as:
Number of people on the train as it left Oxford = Number of people on the train at Slough - Number of people who got off at Slough + Number of people who got on at Slough
Number of people on the train as it left Oxford = 318 - 56 + 134
Number of people on the train as it left Oxford = 396
Therefore, there were 396 people on the train as it left Oxford.
To determine the number of people on the train as it left Oxford, we can work backwards from the information provided.
We know that when the train arrived in London, there were 318 people on the train. This includes the 56 people who got off at Slough and the 134 people who got on at Slough.
To find the number of people on the train as it left Oxford, we need to subtract the people who got off at Slough and add the people who got on at Slough.
So, the number of people on the train as it left Oxford can be calculated as follows:
Number of people on the train as it left Oxford = Number of people on the train in London - Number of people who got off at Slough + Number of people who got on at Slough.
Let's substitute the given values into the equation:
Number of people on the train as it left Oxford = 318 (people in London) - 56 (people who got off at Slough) + 134 (people who got on at Slough).
Now we can calculate the answer:
Number of people on the train as it left Oxford = 318 - 56 + 134 = 396.
Therefore, there were 396 people on the train as it left Oxford.
