complete question:
Juli rides her bike from the sports complex to the school. Then she rides from the school to the mall, and then on to the library. Kyle rides his bike from his house to the mall, and then to the library. Who rides farther? How many miles farther?
Answer:
Juli rides farther than Kyle because She covered a greater distance.
Miles farther = 12/5 - 32/15 = (36 - 32)/15 = 4/15 miles
Explanation:
The picture below is used to answer the question above. Let us use an arrow to demonstrate the route Juli and Kyle covered with their bikes.
Juli's journey
sport complex → school → mall → library
the total distance covered as shown from the diagram is 2/3 miles + 2/5 miles + 1 1/3 miles . The sum of the distance is the total distance Juli covered.
2/3 + 2/5 + 4/3 = (10 + 6 + 20)/15 = 36/15 = 12/5 or 2 2/5 miles
Kyle's journey
house → mall → library . The sum of Kyle's distance according to the diagram is 4/5 miles + 1 1/3 miles.
4/5 + 4/3 = (12 + 20)/15 = 32/15 or 2 2/15 miles
Juli rides farther than Kyle because he covered a greater distance.
miles farther = 12/5 - 32/15 = (36 - 32)/15 = 4/15 miles
