1. A boy cyclist and a girl cyclist are 10 miles apart and pedaling toward
each other. The boyâ€™s rate is 4 miles per hour and the girlâ€™s is 6 miles per
hour. The boy and girl cyclist meet in an hour. A friendly fly is zooming
continuously back and forth from one bike to the other. If the fly's rate is 20
miles per hour, by the time the cyclists reach each other, how far does the
fly fly?
Fill in Polyaâ€™s 4 steps to answer the problem
Step 2_ Make a plan: Step 3_ Execute the plan: Step 4_ Look back and review: a Step1_ Read and
. understand: Two bikes are traveling at 2 b Step1_ Read and
. understand: Two bikes are traveling at 2 c Step1_ Read and
. understand: Two bikes are traveling at 2 different speeds. The
faster will travel farther.
The fly's rate is 20 miles
per hour. different speeds. The
faster will travel
farther. The fly's rate
is 20 miles per hour.
Step 2 _Make a
plan: Draw the bikes and
fly. Look at when the bikes
will meet and how far they
travel and how far the fly
will travel. Step 2 _Make a
plan: Draw the bikes
and fly. Look at when
the bikes will meet and
how far they travel and
how far the fly will
travel. Step 3_ Execute the
plan:
After 1 hour, the girl
will have traveled 6
miles and the boy 4
miles, they will
meet. Determine
where the fly will be in
an hour. You need the
formula d=rt; (6mph
+ 4 mph = 10 mph).
Thus, the fly travels
10 miles. Step 3_ Execute the
plan:
After 1 hour, the girl will
have traveled 6 miles
and the boy 4 miles,
they will
meet. Determine where
the fly will be in an
hour. You need the
formula d=rt; r = 20
mph and t = 1 hour
(6mph + 4 mph = 10
mph). Thus d = 20(1) =
20, so the fly flies 20
miles. Step 4_ Look back and
problem. Does it make
sense that the fly will
fly this distance? Step 4_ Look back and
problem. Does it make
sense that the fly will fly
this distance? different speeds. The
faster will travel farther.
The fly's rate is 20 miles
per hour.
Step 2 _Make a
plan: Draw the bikes
and fly. Look at when
the bikes will meet and
how far they travel and
how far the fly will
travel.
Step 3_ Execute the
plan:
After 1 hour, the girl will
have traveled 6 miles
and the boy 4 miles,
they will
meet. Determine where
the fly will be in an
hour. You need the
formula d=rt; t = 1 hour
(6mph + 4 mph = 10
mph). Thus d = 10(1) =
10, divided by two, so
the fly flies 5 miles.
Step 4_ Look back and
problem. Does it make
sense that the fly will fly
this distance? 7.15 points Question 9
