Question 154031: I previously asked a question regarding chasing someone with a 10 mile head start and I was running at a rate that is two miles per hour faster than the person I was chasing also with a hornet flying back and forth between us at a rate of 20 miles per hour. How far would the hornet fly by the time I reached the other person? Stan did a great job of answering the question for me, 5 hous to catch up to the person and the hornet flew 5X20=100 miles. My problem is that I still can not see how to write this out using the formulas. Any help is appreciated. Thank you.

Question 154640: Dear Algebra.com tutors,
I'm stumped! Can you help with this bonus problem?
How long would a yellow light have to remain lit to allow a car to safely stop before reaching a 100 ft intersection if the car is traveling at a rate of 50 mph when it begins to decelerate at a steady rate of -20 ft/second squared, after a reaction time of 0.6 seconds?
Use the following two physics formulas to aid in solving this problem:
x = v-subzero * t + 1/2 * a * t-squared
and
v-squared = v-subzero squared + 2 * a * x
(x = distance, a = acceleration, v = velocity, t = time, v-subzero = initial velocity)
Thanks for trying! I appreciated it!

Question 156080: I am having difficulty setting up the equation for this problem. Thank you for any help.
An army messenger will travel at a speed of 60 miles per hour on land and in a motorboat whose speed is 20 miles per hour in still water. In delivering a message he will go by land to a dock on a river and then on the river against a current of 4 miles per hour. If he reaches his destination in 4 1/2 hours and then returns to his starting point in 3 1/2 hours, how far did he travel by land and how far by water.
