it takes Pedro 60 seconds to run around a 440 yard track.
how long does it take Juan to run around the track if he and Pedro meet in 32 seconds after they start together in a race around the track in opposite directions
:
Find P's speed: 440/60 = 7.33 yds/sec
Let s = J's speed
:
When they meet, they will have traveled a total 440 yds
:
Write dist equation, dist = speed*time
7.33*32 + 32s = 440
234.67 + 32s = 440
32s = 440 - 234.67
32s = 205.33
s =
s = 6.4167 yds/sec is J's speed
then J's time around the track
= 71.6 seconds
