Answer 1

Step-by-step explanation:

Given: distance-60km, time=1hr,30min= 90mins Speed=d/t= 60/90-2/3 km per min To find time taken to cover a distance of 100km at speed 2/3kmpm, Time= distance-speed =100-2/3 =100×3/2=150 mins

Answer 2

Given:-

• A car travels 60 km in 1 hr 30 min.

To Find:-

• Time will it take to cover a distance of 100 km at the same speed.

Formula Used:-

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

Solution:-

For Speed of the Car:-

Using Formula,

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

Here,

• Distance = 60 Km

• Time = 1 hr 30 min = 1.5 hr

Putting values,

$\sf :\implies\:Speed=\dfrac{60}{1.5}$

$\sf :\implies\:Speed=\dfrac{600}{15}$

$\sf :\implies\:Speed=40\:kmh^{-1}$

Now, Time taken to cover a distance of 100 km:-

Using Formula,

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

Here,

• Speed = 40 km/h

• Distance = 100 km

Putting values,

$\sf :\implies\:40=\dfrac{100}{Time}$

$\sf :\implies\:Time=\dfrac{100}{40}$

$\sf :\implies\:Time=\dfrac{10}{4}$

$\sf :\implies\:Time=2.5\:hrs$

Hence, The car will take 2 hr 30 min to cover a distance of 100 km.
