Amy runs 6 miles in 45 minutes. At the same rate, how many minutes would she take to run 4 miles?
lapo4ka [179]
That would be (4/6) of 45 minutes, or 180/6 minutes, or 30 minutes.




You could also find her rate:  6 miles / 45 minutes, or 8 miles / 60 minutes.

Write an equation of ratios:  

8 mi            4 mi
---------- = ------------
60 min            x

Solving for x:  8x = 240; x = 30 minutes

David spent 1/3 of his money on books. He spent another 1/6 of it on stationery and $50 on a radio. If he had $100 left, how muc
horsena [70]

Answer:

You have to work backwards here

so if you had 100 dollars left and u spent 50 on a radio

100+50=150

Then You spent a 1/6 of it on stationery

So you mustve had 5/6 money left or 150 dollars

so you multiply that to find that

5/6=150/x

5x=900

x=180

so add 30 dolalrs to 150 and you have 180.

the you spent a third

you repeat the same process

the you have ur ANSWER
