Question

11.A car covers a distance of 205.5 km in 1.5 hours. What is the distance covered by it in 1 hour ? Also find the distance covered by it in 4 hours ?

Answer 1

Given:-

• A car covers a distance of 205.5 km in 1.5 hours.

To Find:-

• Distance covered by it in 1 hour.

• Distance covered by it in 4 hours.

Formula Used:-

• ${\boxed{\bf{Speed=\dfrac{Distance}{Time}}}}$

Solution:-

Firstly,

$\sf :\implies\:Speed=\dfrac{Distance}{Time}$

$\sf :\implies\:Speed=\dfrac{205.5}{1.5}$

$\sf :\implies\:Speed=\dfrac{2050}{15}$

$\bf :\implies\:Speed=136.66\:kmh^{-1}$

Distance travelled by it in 1 hour:-

$\sf :\implies\:136.66=\dfrac{Distance}{1}$

$\sf :\implies\: Distance=136.66\:km$

Distance travelled by it in 4 hour:-

$\sf :\implies\:136.66=\dfrac{Distance}{4}$

$\sf :\implies\: Distance=546.64\:km$

Hence, The Distance travelled in 1 hour is 136.66km and distance travelled in 4 hour is 546.64km.
