Question 20

A student investigates how the angle of inclination of a ramp affects the time taken for a toy car to travel a distance of 1.5 m down the ramp. The student records three repeats for each angle. Their results are shown in the table below.

Angle of inclination	Repeat 1 (s)	Repeat 2 (s)	Repeat 3 (s)
$15∘15^\circ$	4.12	4.18	4.15
$30∘30^\circ$	2.89	1.95	2.82
$45∘45^\circ$	1.45	1.48	1.42

Which value is most likely an anomalous result?

$1.42$

$1.95$

$4.18$

$2.89$
