Question 1208219
<br>
The two runners are initially 5.6+4.9 = 10.5km apart; they are running towards each other at a rate of 8.4+7.5 = 15.9km/h.  The time it will take the two to meet is the time it will take the two of them to cover the full 10.5km.<br>
distance = rate * time
time = distance / rate = 10.5/15.9 = 105/159 = 35/53 hours<br>
After 35/53 hours, the position of runner A will be 8.4(35/53) km east of his starting point 5.6km west of the flagpole.  Use a calculator to find his position is (to several decimal places) .05283km west of the flagpole.<br>
After 35/53 hours, the position of runner B will be 7.5(35/53) km west of his starting point 4.9 km east of the flagpole.  Use a calculator to find his position is (to several decimal places) .05283km west of the flagpole.<br>
ANSWER (to several decimal places): .05283 km<br>
Nice problem for learning if the numbers were "nice"; as it is, the problem is mostly a waste of time.<br>
