Question

Q: 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 mph. The next day they travel 7 hours, averaging the same speed. How many miles are left for the family to travel?

Answer 1

distance = speed * time

After two days, the distance the family has traveled is
distance = (45 mi/h) * (6 h + 7 h) = 585 mi

The remaining distance is
850 mi - 585 mi = 265 mi
