Pkease solve its urgent ​

Answer 1

Explanation:

ANSWER:-

Total Speed : Speed gone to the market+ Speed while returning from market.(10+15)=25km/h

Total Time: 40 minutes => 0.6 hours

We know that the formula for deriving the Distance

$speed = \frac{distance}{time}$

$25 = \frac{distance}{0.6}$

$distance = 25 \times 0.6$

Distance= 15 kilometre.

Now, we need to find Average speed.

$average \: speed = \frac{total \: distance}{total \: time}$

$average \: speed = \frac{15}{0.6}$

Average speed = 25 km/h.
