Ryan likes to ride his bike around the block. If he rides out of his house west, the sidewalk circles his block, and brings him back to his doorstep 0.35 miles later. Find his distance and displacement.

Distance = 0.35 miles

Displacement = 0 miles

Explanation:

The distance covered Ryan is the sum of the diatances moved from his house and then back to his house. According to the question, after covering 0.35 miles, Ryan arrived back in his house. Hence, distance covered by Ryan is 0.35 miles.

Displacement refers to overall change in position of an object from a certain starting position.

In the scenario above, Ryan's Displacement from is house will be zero, since ;

Starting position is his house and his final position is his house.

Hence, change in position or distance from his house = 0 miles
