A motorcyclist drives from `A` to `B` with a uniform speed of `30 km h^(-1)` and returns back with a speed of `20 kmh^(-1)`. Find its average speed.

Text Solution

AI Generated Solution

To find the average speed of the motorcyclist, we need to consider the total distance traveled and the total time taken for the entire trip. Let's denote: - Distance from A to B as \( D \) - Speed from A to B as \( v_1 = 30 \text{ km/h} \) - Speed from B to A as \( v_2 = 20 \text{ km/h} \) ### Step-by-Step Solution: ...
