Question

Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?
Use the variable m to represent the number of miles she drove after lunch.

Which equation represents this situation and its solution?

Answer 1

Answer:

68+m=185

m=117

Step-by-step explanation:

68 miles before lunch, plus m miles after lunch is a total of 185 miles. Assuming she reaches her destination. That creates the equation 68+m=185

Then, to figure out the miles she travels after lunch we solve for m:

do this by subtracting 68 from both sides. This leaves us with: m=117
