please help me understand this problem I want answer and I will follow you










here I am giving 10 points so please answer don't just put something ​

Answer 1

Distance travelled by car is

$= x+x=2×x$

Time taken by car to go to Thane is

$= \frac{x}{40}$

Time taken by car for return journey is

$= \frac{x}{60}$

Total time taken is equal to

$= \frac{x}{40} + \frac{x}{60} = \frac{x}{24}$

Average speed is equal to total distance travelled by car divided by total time taken.

so, average speed is equal to

$\frac{2 \times x}{ \frac{x}{24} } = 48 \: km \: per \: hr$

Answer 2

48 km per hour

hope it helps you
