Halina cycled from A to B at an average speed of 26 km per hour. She then cycled from B to C at an average speed of 20 km per hour.
She left A at 10.00 am, did not stop at B and arrived at C at 3.00 pm.
It took Halina x hours to cycle from A to B.
Explain why the distance from A to B, in kilometres, is 26 x.
[1]
Write down an expression, in terms of x, for the time taken to cycle from B to C.
[2]
Hence show that the distance from B to C, in kilometres, is 100 – 20 x.
