Question

John took 45 minutes to bicycle to his grandmother's house, a total of four kilometers. What was his velocity in km/hr?

Answer 1

`5.3` `km`/`hr`

Explanation:

`"Speed per minute"`= `4/ 45.=0.088888` `km`/`min`.
so in 60 minutes, distance traveled will be `60 xx 0.088888 = 5.3` `km`/`hr`
