Problem Analysis

To solve this problem, we need to find the ratio between the distance traveled on foot and the distance traveled by bus. We also need to determine the fraction of the total distance traveled that was covered by bus.

Solution

Let's start by calculating the ratio between the distance traveled on foot and the distance traveled by bus.

The distance traveled on foot is given as 5.6 km, and the distance traveled by bus is given as 12.6 km. To find the ratio, we divide the distance traveled on foot by the distance traveled by bus:

Ratio = Distance Traveled on Foot / Distance Traveled by Bus

Ratio = 5.6 km / 12.6 km

Calculating this ratio, we find that the distance traveled on foot is approximately 0.4444 times the distance traveled by bus.

Next, let's determine the fraction of the total distance traveled that was covered by bus. To do this, we need to calculate the total distance traveled by adding the distance traveled on foot and the distance traveled by bus:

Total Distance Traveled = Distance Traveled on Foot + Distance Traveled by Bus

Total Distance Traveled = 5.6 km + 12.6 km

Calculating this, we find that the total distance traveled is approximately 18.2 km.

To find the fraction of the total distance traveled that was covered by bus, we divide the distance traveled by bus by the total distance traveled:

Fraction of Distance Traveled by Bus = Distance Traveled by Bus / Total Distance Traveled

Fraction of Distance Traveled by Bus = 12.6 km / 18.2 km

Calculating this fraction, we find that approximately 0.6923 or 69.23% of the total distance traveled was covered by bus.

Answer

Therefore, the ratio between the distance traveled on foot and the distance traveled by bus is approximately 0.4444. Additionally, approximately 69.23% of the total distance traveled was covered by bus.
