Thabo uses the time ticker to determine his average walking speed. He has to drop off a package to his grandmother. It is 4km to his grandmothers house and another 2.5 km from her house to thabo's house. Could I please get help on this

Please clarify your question..

I have sent an attatchment, hopefully it could help

Okay, since this is an assignment, that means you have done mechanics at school. What have you come up with? I don't care if it's wrong or not, just show what you tried.
