Problems leading to Simultaneous equations
I have a problem bringing out the equations here
It t akes a student 12minutes to et to the class from the sporting groung if she waks at 1.5m/s and runs at 3m/s. Had she walked half as far, she should have taken 8minutes. Find the di stance between the school and the classroom.
Pls can i have some help?Thanks in advance

Re: Problems leading to Simultaneous equations
If she had walked all the way (without running at all), she would have taken 16 minutes, or 16 × 60 = 960 seconds. Hence the distance between the sports ground and the classroom is 1.5 × 960 = 1440 metres.
