Your father will be going to your grandparents house for dinner.he drives 40 minutws at a constant soeed of 30 miles per houer.he reaches the highway,quickly speeds up,and drives for another 30 minutes at a constant speed of 60 miles per hour.how far did you and your father travel altogether?

40 minutes is 2/3 of an hour.

30 miles per hour x 2/3 hour = 20 miles.

30 minutes = 1/2 hour.

60 miles per hour x 1/2 hour = 30 miles.

Total = 20 + 30 = 50 miles.
