two cars 270 mi. apart enter an interstate highway traveling towards one another. one car travels at 65 mph and the other at 55 mph. when will they meet
no idea. when did they start?
However, if you want to know how long it took them to meet, that would be
time = distance/speed = 270/(65+55) = ? hours
r1*t + r2*t = 270.
65*t + 55*t = 270,
t = ?
To find out when the two cars will meet, we can use the concept of relative speed. The relative speed is the sum of the speeds of the two cars traveling towards each other. In this case, the relative speed is 65 mph + 55 mph = 120 mph.
We also know that the cars are initially 270 miles apart. To determine when the cars will meet, we can use the formula:
Time = Distance / Speed
In this case, we want to find the time it takes for the two cars to cover a total distance of 270 miles when traveling at a relative speed of 120 mph.
Time = 270 miles / 120 mph
Simplifying this calculation, we find:
Time = 2.25 hours
Therefore, it will take 2.25 hours for the two cars to meet each other.
