The scenario is that I start from point A and am heading to point B which is 280 miles away. After 1.5 hours, I have driven 105 miles.\r

I know that this is a linear function (constant), so I used the information given to fill in the chart. For every 30 minutes driven, I know that I am going 35 miles (or, 70 MPH), and that it will take me 4 hours total. What I don't know, is how to actually write this in the correct linear format. Is it just: D(t) =105/1.5? Thank you for your help! \n" ); document.write( "

You can put this solution on YOUR website!
If speed is constant, Then distance D and time T give speed R as $\"D%2FT=R\"$ . this is the same as $\"D=RT\"$ . \n" ); document.write( "
