Answer:
1000m/h
Step-by-step explanation:
You figure out both of the cyclists km/h times but converting their distance in the 12 hours into a rate
Mike McNamara:
[tex]\frac{445}{12}[/tex]
Beryl Burton:
[tex]\frac{446.2}{12}[/tex]
You then divide the denominator (12) by itself so that it becomes 1
Mike McNamara:
[tex]\frac{445}{12}[/tex] = [tex]\frac{445/12}{1}[/tex]
Beryl Burton:
[tex]\frac{446.2}{12}[/tex] = [tex]\frac{446.2/12}{1}[/tex]
You then divide the numerators by what you divided the denominator by (12) to get the km/h
Mike McNamara:
[tex]\frac{445}{12}[/tex] = 37.08km/h (rounded to two decimal places)
Beryl Burton:
[tex]\frac{446.2}{12}[/tex] = 37.18km/h (rounded to two decimal places)
You them have to convert km/h to m/h by multiplying the numerators (37.08 & 37.18) by 1000 to get the distance in metres
Mike McNamara:
37.08 x 1000
= 37080m
=37080m/h
Beryl Burton
31.18 x 1000
= 37180m
= 37080m/h
Therefore Beryl Burton's average speed was faster than Mike McNamara's by 1000m/h
