Question

A sport car runs at a speed of 92.4 km/h. Find the distance travelled in 10 minutes

Answer 1

Answer:

$\sf{The \ distance \ travelled \ in \ 10 \ minutes}$

$\sf{is \ 15.4 \ km}$

Given:

• A sport car runs at a speed of 92.4 km/h

To find:

• The distance travelled in 10 minutes.

Solution:

$\sf{Let \ the \ distance \ cover \ in \ 10 \ minutes}$

$\sf{be \ x.}$

$\sf{1 \ hr=60 \ minutes}$

$\sf{It's \ in \ direct \ proportion.}$

$\sf{\dfrac{92.4}{60}=\dfrac{x}{10}}$

$\sf{\therefore{x=\dfrac{92.4}{6}}}$

$\sf{\therefore{x=15.4}}$

$\sf\purple{\tt{\therefore{The \ distance \ travelled \ in \ 10 \ minutes}}}$

$\sf\purple{\tt{is \ 15.4 \ km}}$

$\sf{In \ direct \ proportion, \ \dfrac{x}{y} \ is \ constant.}$

$\sf{In \ inverse \ proportion, \ xy \ is \ constant.}$
