Compute all parts of given problem:
Problem: Consider a moving sidewalk, such as the ones commonly found in airports. For one particular such moving sidewalk you notice that it takes you 75.0 s to ride while standing from one end to the other. You also note that if you walk next to the moving sidewalk, instead of on it, it takes you 50.0 s to walk from one end to the other.
Part A: How long would it take you to go from one end to the other if you walked while riding the moving sidewalk?
Part B: How long would it take you if you walked on the moving sidewalk in the opposite direction that it was moving?
Please provide a full detailed explanation for the solution. Thanks.
