how long will it take 2 people 600 feet apart to meet, if both are are walking towards each other at a constant speed of 3mph?

Question

just a small part of a much larger larger question

Answer 1

3 mph = 3(5280)/3600 ft/sec

= 4.4 feet per second

each walks 300 feet before they meet

d=rt

t = d/r = distance divided by rate of speed = time

300 feet take 300/4.4 = 3000/44 =750/11 = 68 2/11 seconds

Answer 2

To meet in the middle, each person will have to walk 300 feet (1/2 the total distance)

There are 5280 feet/mile

300 feet x 1 mile/5280 feet = 0.05682 miles each has to walk

0.05682 miles x 1 hour/3 miles = 0.01894 hours

0.01894 hours x 60 min/hours = 1.14 minutes

1.14 minutes x 60 seconds/minute = 68 seconds
