Question

To go to school in the morning, I first walk to the garden shed at 6km/h to collect my bicycle. I then cycle to school at 15 km/h. The total journey normally takes 18.5 minutes. One day, I am late and I run to the shed at 18km/h and cycle at 27km/h. The journey takes me 10 min 10 s. How far is it from my house to the garden shed?

Answer 1

Answer:

I don't know try something different

Answer 2

Answer:

Let the distance be x km

Then, x8 - 2.560 = x10 + 560

x8 - x10 = 560 + 2.560

=> 2x80 = 7.560

=> x = 7.5×802×60 = 5 km
