Two motor ships set off from two ports towards each other. One swam at a speed of 90 km / h. Write down the literal expression with which you can find out what distance the second sailed if they met in c hours, and the distance between the ports was 1227 km?

1. Since the first motor ship sails at a speed of 90 km per hour, we write down the distance that it will sail in one hour. For this, the speed should be multiplied by the travel time. We get:

90 * s km.

2. And since we know that initially the distance between the motor ships was equal to 1227 km, and as a result they met, therefore we can write down how far the second motor ship passed to the meeting. To do this, it is necessary to subtract from the total distance the distance that the first motor ship sailed.

1227 – 90 * s km.
