Question

Each day Kim jogs from her home to the lake and then walks back again along the same route. Her average speed is 5m/s. And 2m/s while walking. If the whole trip takes 35 minutes, how far is it from Kim's home to the lake?

Answer 1

I think the answer is 3.5 m but i don't know if i'm exactly accurate....because what i did was 5x2=10 and then i did 35/10 and got 3.5... hope this helps any  ^-^...
