Front

What is the formula to calculate distance?

Back

The formula to calculate distance is d = rt, where d is distance, r is rate of speed, and t is time.

Front

If a car travels at 70 miles per hour for half an hour, what is the distance traveled?

Back

The distance traveled is (70)(1/2) = 35 miles.

What equation represents Elton's weight loss over time if he starts at 218 pounds and loses 5 pounds each week?

Back

The equation is p = 218 - 5t, where p is weight and t is time in weeks.

Front

What equation represents Steven's weight loss over time if he starts at 186 pounds and loses 1 pound each week?

Back

Back

The relationship is given by the formula d = rt.

Front

If a car travels for 2 hours at a speed of 60 miles per hour, what is the distance traveled?

Back

The distance traveled is d = rt = 60 * 2 = 120 miles.

Front

What is the meaning of an inequality in mathematics?
