Afamily's vacation destination is 850 miles from their home. they travel by car 6 hours on the first day of their trip. their average speed is 45 mph. the next day they travel 7 hours, averaging the same speed. how many miles are left for the family to travel?

The distance traveled is equal to the product of the speed and the time. For the first day,
                                      d = (45 mile/h)(6 h) = 270 miles
On the second day,
                                      d = (45 mile/h)(7 h) = 315 miles
The total distance traveled after 2 days is equal to 585 miles. Subtracting this value from the given distance will give us an answer of 265 miles.
