Answer:
Let x = Leah's speed.
So, rate*time = distance and they are both going the same distance.
Now, we have x*3 = (x + 10)*1
The left side is Leah's distance and the right side is May's distance. Her rate is x + 10 since she is going to km/h faster than Leah.
So, we solve the equation 3x = x + 10 for x.
Subtracting x from both sides yields: 2x = 10, so x = 5.
Leah's going 5 km/h and May is going 10 faster: 15 km/h
