Bob travels from Inglewood to Anytown, a distance of 20kilometres, he walks 800 metres and bicylces the rest of the way. what percentage does he travel by bicylce?

Respuesta :

carlosego

For this case we have the following conversion:

[tex] 1 km = 1000m
[/tex]

Therefore, for 20 kilometers we have:

[tex] (20) (1000) = 20000 m
[/tex]

Then, we have the following relationship:

[tex] 800 + x = 20000
[/tex]

Where,

x: distance Bob travels by bicycle

Clearing x we have:

[tex] x = 20000 - 800

x = 19200
[/tex]

Then, the percentage that Bob travels by bicycle is:

[tex] (\frac{19200}{20000}) * (100) = 96 [/tex]%

Answer:

The percentage that Bob travels in bicycle is 96%.
