Sohil has $18 in quarters and loonies. If there are 27 coins in total, how many loonies are there

15 loonies = $15.00

12 quarters = $3.00

CHECK:

15+12=27

3+15=18

So there are 15 loonies :)

You need the formula: feet per second = feet/second
Now you have to recast the formula to:
feet per second * second = feet , because you want to know the number of feet.

At the bottom is the answer.

At last you have to insert the values:
28 feet per second * 20 seconds = 560 feet
