Dina and masha started out on a 10 km bike path at the same time. when dina reached the end of the 10 km, masha still had 2 km to bike. if dina's biking speed was 5km/h, find masha's biking speed

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

Now let us find Masha's biking speed.

Therefore, Masha's biking speed is 4 km per hour.
