Assuming that these two cars start from the same departure point and go in the same direction, try to draw a picture and also form a data table.
___________________speed_____________time____________distance
CAR1________________7
CAR2_______________60
Stop and think: Car 1 is ahead of car 2 at the initial time. Car 2 is closing the distance between the two cars at rate of 60-7=53 miles per hour. In other words, the two cars are approaching each other at 53 miles per hour.
Use speed in MILES per HOUR; time in HOURS, and convert the distance to be covered as MILES.
miles
miles
miles
Rule for uniform travel rates is RT=D for rate time distance.
HOURS
but you really want this as minutes or seconds.
SECONDS
You can go through this and generalize for any value you want as variables.
Notice I did not continue with the data table.
