Wendy travelled 300 km. She travelled part of the way (a distance of x km) by bus and arrived at the train station just in time to complete her journey by train. The average speed of the bus was 40 km per hour and on average the train travelled 20 km per hour faster than the bus. The entire trip took 5 hours.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
