Mr. And Mrs. Storey drove 3,200 miles in all during their vacation. Mr Storey drove 3 times as many miles as Mrs. Storey. Howany
miles did Mr. Storey drive? How many miles did Mrs. Storey drive?
1 answer:
If the ratio of miles is
.. mr : mrs = 3 : 1
The total number of "ratio units" is 3+1 = 4, so each one stands for 3200/4 = 800 miles.
Mr Storey drove 3*800 = 2400 miles
Mrs Storey drove 1*800 = 800 miles
