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 1_ Read and understand:

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

review: Reread the

problem. Does it make

sense that the fly will

fly this distance? Step 4_ Look back and

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

review: Reread the

problem. Does it make

sense that the fly will fly

this distance? 7.15 points Question 9
