They arrive at LaTanya's house at 3:30PM. How far is Marta's house from LaTanya's house? What is the equation you will use?

Answer 1

To find the distance between LaTanya's house and Marta's house, we can use the equation Distance = Speed x Time. LaTanya bikes at 12 mi/h for 1.5 hours, so the distance is 18 miles.

Step-by-step explanation:

To find the distance between LaTanya's house and Marta's house, we can use the equation Distance = Speed x Time.

First, we need to find the time it takes for LaTanya to bike to Marta's house. She bikes at a speed of 12 miles per hour. Since she leaves at 12:30 PM and arrives at Marta's house 90 minutes later, we convert the time to hours by dividing 90 minutes by 60: 90/60 = 1.5 hours.

So the distance from LaTanya's house to Marta's house is: Distance = Speed x Time = 12 mi/h x 1.5 h = 18 miles.
