Distance between Davien's school and beach, D = 50 km.

Also, Davian's house is 10 km closer to the beach than the school.

So, distance between Davien's house and beach, d = 40 km.

Speed of Davian, s = 40 km/h.

Now, time taken is given by :

$t =\dfrac{Distance}{Speed}\\\\t=\dfrac{40}{40}=1\ hour$

Therefore, Davien reach the beach at 1 : 30 P.M .

Hence, this is the required solution.
