If two cars started out at the same spot and traveled in opposite directions for 90 minutes at 60miles per hour -far apart in total miles would they be at the end of the 90 minutes?

they travel for 1.5 hours, at a combined rate of 120 mi/hr, so ...

To find out how far apart the two cars would be at the end of the 90 minutes, we need to calculate the distance traveled by each car during that time.

First, let's calculate the distance traveled by one car. Since both cars are traveling at 60 miles per hour, in 90 minutes (which is 1.5 hours), one car would cover a distance of:

Distance = Speed x Time
Distance = 60 mph x 1.5 hours
Distance = 90 miles

Now, since the two cars are traveling in opposite directions, the total distance between them would be the sum of the distances covered by each car. Therefore, the total distance between the two cars after 90 minutes would be:

Total Distance = Distance + Distance
Total Distance = 90 miles + 90 miles
Total Distance = 180 miles

So, at the end of the 90 minutes, the two cars would be 180 miles apart.
