Question

Car 1 is going 75mph and is 7 miles ahead of car 2 which is going 85mph. How long until car 2 passes car 1?

Answer 1

Answer:

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?

it takes 7/10 of an hour.. correct :)

.7 * 60 = 42 minutes

in 42 minutes car 2 will pass car 1
