Keisha drove 495 miles in 9 hours at the same rate how many miles would she drive in 7 hours
in 9 hours drives 495 miles
in 1 hour drives 495/9 miles
in 7 hours drives (459/9) x 7 miles.
+36919 Another problem which MIGHT be clearer to you as a RATIO
495 miles / 9 hours = x / 7hours
SO:
x= 495 miles /9 x 7 (the hours 'cancel') and you are left with = 385 miles
