Alec's dad runs 10 time than I do do, i ran 7 timeeeeeeeeeeeees
more than my baby sister. If my baby sister ran 4 meters, how far did Alec's dad run?
Let's call the distance Alec's dad ran "D".
We know that Alec's dad runs 10 times as much as you, so:
D = 10 * (the distance you ran)
We also know that you ran 7 times as much as your baby sister, so:
(the distance you ran) = 7 * 4 meters
Substituting this into the first equation, we have:
D = 10 * (7 * 4 meters)
Simplifying this, we get:
D = 280 meters
Therefore, Alec's dad ran 280 meters.
