Hudson is already 40 mi away from home. He is driving 65mi/h. Write an equation that models the total distance d travelled after h hrs.

Answer 1

Hi Muhammad,

 

Start off with what you know (for this problem, it really helps to keep track of your units):

d: distance from home= 40 miles

v: velocity= 65 miles/ hour

 

what you want to know is the total distance he traveled (D) after h hours

So, to set up your problem, it would look something like this:

 

D= v*h + d    or

D= (65 miles/ hour)(h hours) + 40 miles

Notice how your hours cancel each other out and you're left with miles for your total distance.

 

I hope this helps and good luck!
