an ostrich can run a maximum speed of 70km per hour.

You have to convert the 70km to 70000m.
you have to convert the per hour part too and 1hr =60 min.

Somehow the time becomes 3600, could someone please tell me how?

  1. If you want to convert 70km/h to m/s:

    70km/h = 70,000m/3600s =

    1 hour = 3600s.
