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?

A) 225 miles
B) 265 miles
C) 285 miles
D) 345 miles

Respuesta :

for the first part:

distance= speed * time
distance=6*45
=270

for the second part:

distance=speed*time
distance=7*45
=315

total-distance already traveled = distance left
850-315-270=265
distance left=265 miles

The answer is B.
Hope this helps! :)
