23 Sam drives his car on a journey.

Here is the travel graph for the first 15 minutes of his journey.

(a) Work out Sam’s speed, in km/h, for the first 15 minutes of his journey. (2)

At 10 15 Sam stops for 10 minutes and then drives for 20 minutes at a speed of 75 km/h.

(b) On the grid, complete the travel graph for Sam’s journey. (3)

Answer	Mark	Mark scheme
80	M1	for a complete method eg \(\dfrac{20}{15} \times 60\) or \(20 \times 4\) or \(20 \div \dfrac{1}{4}\)
80	A1	cao

Answer	Mark	Mark scheme
Travel graph	M1	for method to find distance travelled in last 20 minutes, eg \(75 \times \dfrac{20}{60}\ (= 25)\)
	C2	for a fully correct travel graph
	(C1	for horizontal straight line from (10 15, 20) to (10 25, 20) or for a line of the correct length and gradient to indicate a speed of 75 km/h eg straight line from (10 25, 20) to (10 45, 45))
