Paper 2 H - SAMPLE SET 1 Q1
1) Four students tested their reaction times using a computer program.
When a green light appeared on the screen the students had to press a key.
Table 1 shows their results.

Reaction time is important at the start of a race.
Table 2 shows the time taken by a boy to run different distances.
1.5) Reaction time is more important in a 100 m race than in an 800 m race.
Explain why. [2 marks]
Two girls, A and B, ran an 800 m race.
Figure 1 shows how the distance changed with time.
Explain why. [2 marks]
Two girls, A and B, ran an 800 m race.
Figure 1 shows how the distance changed with time.
