Two trains leave stations 320 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour while the other travels at 95 miles per hour. How long will it take for the two trains to meet?

1.6 hours / 1 hour 36 minutes

Step-by-step explanation:

105+95=200 miles

This is the distance that the trains could travel in an hour.

320÷200=1.6 hours

Our Answer is 1.6 hours / 1 hour 36 minutes

The problem ask to calculate the growth rate after 8 hours base on the statement that you give. So with the data given, where as the population would be grow in 20 minutes, the possible growth rate in 8 hours would be calculates as 65X8^tXln8.
