A man covers 500 m on foot, 30 km on the bike and 70 km by car. What percent of his total journey is covered on foot?4.97%49.75%0.49%0.04%

First, we need to convert all distances to the same unit. In this case, we'll convert everything to meters because the distance covered on foot is given in meters.

1 km = 1000 m

So, 30 km on the bike is 30,000 m and 70 km by car is 70,000 m.

The total distance covered is the sum of all these distances:

500 m (on foot) + 30,000 m (on bike) + 70,000 m (by car) = 100,500 m

Next, we find the percentage of the total distance that was covered on foot. The formula to find the percentage is:

(Distance on foot / Total distance) * 100%

So, (500 m / 100,500 m) * 100% = 0.497%

So, the man covered approximately 0.497% of his total journey on foot. The closest answer to this is 0.49%.
