Step-by-step explanation:
Let's call the rate of the slower hiker "x" mph.
The faster hiker walks 1.1 mph faster than the slower hiker, so their rate is "x + 1.1" mph.
Now, we know that distance = rate × time. In this case, both hikers are walking towards each other, so we can add their distances to get the total distance of 22 miles:
Distance of the slower hiker + Distance of the faster hiker = Total distance
4x + 4(x + 1.1) = 22
Now, let's solve for x:
4x + 4x + 4.4 = 22
Combine like terms:
8x + 4.4 = 22
Subtract 4.4 from both sides:
8x = 22 - 4.4
8x = 17.6
Now, divide by 8 to find the rate of the slower hiker:
x = 17.6 / 8
x = 2.2 mph
So, the slower hiker's rate is 2.2 mph, and the faster hiker's rate is:
x + 1.1 = 2.2 + 1.1 = 3.3 mph
Therefore, the slower hiker walks at 2.2 mph, and the faster hiker walks at 3.3 mph.
