Answer 1

${\blue{\underline{\underline{\bold{\huge{Given:-}}}}}}$

✏ A car covers a distance in 20 minutes.

✏ Speed of the car is 30 km per hour.

✰ We have to find out the value of speed to cover same distance in 40 minutes.

${\blue{\underline{\underline{\bold{\huge{Solution:-}}}}}}$

✏ Case 1:-

Here,

time = 20 minutes

= 20/60 hour

= 1/3 hour

Hence,

☞ Distance = Speed × Time

= 30 × 1/3

= 10 km

✏ Case 2:-

time = 40 minutes

= 40/60

= 2/3 hour

Hence,

☞ Speed = distance /time

= 10 / 2/3

= 15 km per hour

Therefore, the average speed to cover the same distance in 40 minutes is 15km per hour.
