Xiaohong walked from home to school for 10 minutes, walking 60 meters per minute. How many meters is Xiaohong's home from the school?

60×10=900 (meters)

distance = speed × time

Which one do you think is better? Why?

65×6+75×6 (65+75)×6

1. From the perspective of thinking, the first method is to first find the distance traveled by two people in 6 minutes, and then find the distance traveled by both people together, that is, the entire distance. The second idea is to first find the distance traveled by two people in 1 minute, and then calculate the distance traveled in 6 minutes.

2. From the formal comparison, the first is a three-step calculation, and the second is a two-step calculation. The second solution is one step less than the first solution and is simpler in form.
