Hey Brady! It's me Steve, do you wanna go to the grocery store with me ?
I'd love to go and , but how far is the store since my parents told me that I can't go farther than 7 miles in my car ?
Well, if you pass by my place which 4 miles then go straight towards the grocery store which is 5 miles, that would take 9 miles which is past your limit
Yeah your right!! So what do you suppose I could do in order to approach the grocery store without passing 7 miles ?
Hmm... I might have a solution but let me sort it out before you do anything.
Brady's house
?
4 miles
Brady's house is 6.4 miles away from the grocery store. Therefore he is eligible to go without breaking the limit.
