Jennie left home on her bicycle for a long distance ride.
Pam left 3 hours later on her motorcycle carrying her lunch.
Pam traveled at 42 mph and caught jeannie in 1.5 hours.
How fast was jeannie traveling?
:
let j = J's speed
When P catches J, they will have traveled the same distance
write a dist equation; dist = speed * time
:
J's travel time is 3 hrs longer than P's (4.5 hrs)
:
4.5j = 1.5(42)
4.5j = 63
j =
j = 14 mph is J's speed
:
:
We can confirm this by finding the distance each traveled, it should be equal
42*1.5 = 63 mi
14*4.5 = 63 mi
