Question

When Imani walks to school, it takes her one less minute than five times the amount of time it takes her to ride her bike to school. It takes Imani three minutes to ride her bike to school. Write a numerical expression to describe the amount of time it takes Imani to walk to school.

Answer 1

The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.

How do we derive a numerical expression?

Let:

x = amount of time it takes Imani to walk to school

y = amount of time it takes Imani to ride to school = 3 minutes

The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:

x = 5y - 1

Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:

x = (5 * 3) - 1 = 15 - 1 = 14 minutes
