HMH Into Math Grade 6 Module 4 Answer Key Fluency with Multi-Digit Decimal Operations
What’s the Best Route?
A race will be held downtown. The diagram shows the lengths of the streets available for the race.
Plan a route that is approximately 10 kilometers long.
A. The race should begin and end at lettered points on the map. Trace your route on the map. Circle the starting and ending points.
B. What is the total length of your race route? ____ kilometers
Answer:
BC = 0.8 km
DE = 1.7 km
FG = 1.2 km
HJ = 0.5 km
BC + DE + FG + HJ = 0.8 + 1.7 + 1.2 + 0.5 = 4.2 km
Thus the total length of your race route is 4.2 kilometers.
