use the Dist = rate * time , formula.. I call it the dirt formula ( Di = rt )
Step-by-step explanation:
since the cars are closing their distance at 10 MPH.. this is question wants to know how long before the cars pass when they are 7 miles apart... this would be the same for a car going 10 MPH and needs to get to a location 7 miles away. sooo..
how long does it take to travel 7 miles at 10 MPH?
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
