Hey mate!!!

 <b >Here is your answer ;</b >

Let the time taken to reach the destination be  <b >x </b > min.

Speed1 is 24 km/h
Time more taken, t1 = 5.

Then, distance is speed * time

=  \frac{24 * (x + 5)}{60}

=  \frac{2 * (x + 5)}{5} _eq1


Also,
Speed2 is 30km/h
Time less taken, t2 = 4.

Then, distance is speed * time

=  \frac{30 * (x - 4)}{60}

=  \frac{1 * (x - 4)}{2} _eq2

By comparing eq1 and eq2.

We get,


 \frac{2 * (x + 5)}{5} = \frac{1 * (x - 4)}{2}

==>> 4(x + 5) = 5(x - 4)

==>> 4x + 20 = 5x - 20

==>> x = 40 mins.


Now placing  x in eq2, we can get the distance as;

 \frac{(x - 4)}{2}

= \frac{(40 - 4)}{2}

= \frac{(36)}{2}

= 18 km.
