Measure the time it takes you to walk from your house to your bus stop or the school. If you consider that your average walking speed is `4 kms per hr` estimate the distance of the bus stop or school from your house.

Explanation

it takes 15 minute to reach the school.
15 minute = 15 `xx` 60 = 900 s
Average walking speed is 4 km`h^(-1)` `= (4 xx 1000 m)/(60 xx 60 s) `
Speed `= ("Distance")/("Time")`
`therefore` Distance Speed `xx` Time
`= (4 xx 1000)/(60 xx 60) xx 900 m`
`= 1000 m = 1km`
The school is at a distance of 1 km from your house.
Note: To convert `km h ^(-1)` into `ms ^(-1),` multiply it by `(5)/(18).`
