Adiesel train left berlin and traveled north at an average speed of 25 km/h. a cattle train left at the same time and traveled in the opposite direction with an average speed of 35 km/h. find the number of hours the cattle train needs to travel before the trains are 600 km apart.

10 hours

Step-by-step explanation:

Let represent the distance the train heading north has traveled

Let represent the distance the train heading south has traveled

Let represent the number of hours that has passed

4+4+2x

or

2x+8

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
