Dina and Masha start out on a bike path 10 km long at the same time. When Dina reaches the end of the 10 km, Masha still has 2 km left to bike. If Dina’s biking speed is 5 km/h, find Masha’s biking speed.

10/5 = 8/m

2 = 8/m

m = 4km/hr

The answer is 24 minutes everyone :)

To solve this problem, we can use the formula:

Speed = Distance / Time

We know that Dina's biking speed is 5 km/h and the distance is 10 km. We need to find Masha's biking speed, so let's call it "x" (in km/h).

Let's calculate the time it takes for Dina to bike the distance:

Time = Distance / Speed = 10 km / 5 km/h = 2 hours.

Now, since Dina takes 2 hours to bike the entire 10 km, and Masha still has 2 km left to bike when Dina reaches the end, Masha must have taken 2 hours to bike the 8 km (10 km - 2 km).

We can use this information along with the formula to find Masha's speed:

Speed = Distance / Time = 8 km / 2 hours = 4 km/h.

Therefore, Masha's biking speed is 4 km/h.
