Its homework time again.
This time, lets tackle an interesting & everyday problem.
Lets introduce our protagonist of the story – Jack.
Jack likes long road trips, smell of freshly brewed Colombian coffee, clicky-clack sound of his computer keyboard. He hates toll plazas (they slow him down) & Potassium permanganate.
And oh yes, Jack is obsessive about analyzing every little bit of data in his life.
That brings us to the recent road trip he took.
It was a total of 600 miles.
And Jack tracked the speed at which he was covering every 50 mile distance.
The data is neatly typed in to an Excel workbook (snapshot below), in the range A2:A13.
The problem – what is Jack’s average speed?
At the end of the trip, Jack wants to know what his average speed is.
But his Excel skills are mediocre. So he approached you, an awesome analyst in the making.
Your mission, if you choose to accept, is this:
Figure out which formula calculates average speed and post it in the comments section
So what are you waiting for. Open up Excel, solve the problem and share your answers here. Make Jack happy.
