Mr. Richardson is driving to a town 85 miles away. He drives 35 miles per hour for 2 hours before stopping for lunch. He drives 6 more miles and stops for gas. Which expression shows how many miles, m, Mr. Richardson has left to drive?

Answer 1

After driving for 2 hours at 35 miles per hour, Mr. Richardson has already covered a distance of 2 x 35 = 70 miles.
After stopping for lunch and driving an additional 6 miles, his total distance traveled becomes 70 + 6 = 76 miles.
The expression for the remaining distance, m, is:
m = 85 - 76
m = 9 miles
