100 ml
1.000 m slope what is the slope. for this question?

The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph

Explanation

One hiker walks 3.3 mph faster than the other.

Suppose, the speed of the slower hiker is mph.

So, the speed of the faster hiker will be:  

Both hikers are walking toward each other and meet in 10 hours.

We know that,  

So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours miles.

Given that, they were 77 miles apart in the beginning. So the equation will be ...

Thus, the rate of the slower hiker is 2.2 mph and the rate of the faster hiker is (2.2 + 3.3) mph = 5.5 mph
