Question

joan travels 65 miles per hour for x hours an monday. on tuesday she drives 55 miles per hour for (x+3) hours. write a simplified expression for the sum of the distance travelled. (4mks)

Answer 1

We multiply 65mph by x hours and get 65x miles. We multiply 55mph by x+3 hours and get 55(x+3) miles. Simplifying, we get 55x+165 miles. Adding Mondays and Tuesdays miles, we get 120x+65 miles.

So, 120x+165 miles is our answer.
