Problema Solution
Roger can run 1 mile in 12 minutes. Jeff can run 1 mile in 9 minutes. If Jeff gives Roger a 1 minute head start, how long will it take Jeff to catch up to Roger? How far will each run?
Answer provided by our tutors
We can write 2 equations using the general equation d=rt (distance=rate*time):
Roger:
d=(1/12)(t+1)
Jeff:
d=(1/9)(t)
Using Algebrator to solve for t and d, we get:
t=3minutes
d=1/3 mile
