Question

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?

Answer 1

For this case we have the following conversion:

$1 km = 1000m$

Therefore, for 20 kilometers we have:

$(20) (1000) = 20000 m$

Then, we have the following relationship:

$800 + x = 20000$

Where,

x: distance Bob travels by bicycle

Clearing x we have:

$x = 20000 - 800\\x = 19200$

Then, the percentage that Bob travels by bicycle is:

$(\frac{19200}{20000}) * (100) = 96$%

Answer:

The percentage that Bob travels in bicycle is 96%.
