Question

A family’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 miles per hour. The next day they travel 7 hours, averaging the same speed. How many miles are left for the family to travel?

Answer 1

6x45=270, 7x45=315, 270+315=585, 850-585=265

265 miles left

Answer 2

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.
