Question

Arica can run 1/6 of a kilometer in a minute her school is 3/4 A kilometer away from her home At this speed how long will it take Erica to run from home to school

Answer 1

Erica will take 4.5 minutes to run from home to school

Solution:

Given that , Arica can run
`(1)/(6)` of a kilometer in a minute

Her school is
`(3)/(4)` th of a kilometer away from her home

We have to find at this speed how long will it take Erica to run from home to school

The relation between speed distance and time is given as:

`\text { Distance }=\text { speed } * \text { time }`

Plugging in values, we get

`(3)/(4)=(1)/(6) * \text { time taken }`

`\begin{array}{l}{\text { Time taken to reach school }=(3)/(4) * 6} \\\\ {\text { Time taken to reach home }=(3)/(2) * 3} \\\\ {\text { Time taken to reach home }=(9)/(2)=4.5}\end{array}`

Hence, she takes 4.5 minutes to reach school from her home
