Question

A band marches 2 1/2 miles in 1 2/3 hours at a juneteenth parade. They march at the same rate in a fourth of july parade for 1/2 hour. How far does the band march in 1/2 hour?

Answer 1

Using proportions, it is found that the band marches 0.75 miles in half an hour.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

According to the information given in the problem, the following rule of three can be built:

2.5 miles - 1.67 hours

x miles - 0.5 hours.

Applying cross multiplication, we have that:

1.67x = 2.5(0.5)

x = 2.5(0.5)/1.67

x = 0.75 miles

The band marches 0.75 miles in half an hour.
