We know that 1 foot = 12 inches and 1 minute = 60 seconds, so to convert 60 inches per second to feet per minute, we are going to multiply
by
and
to cancel units and express our answer in feet per minute:
We can conclude that after converting 60 inches per second to <span>feet per minute, we get 300 feet per minute.</span>
Send me the name of the homework
Hello,
Let a the greater number
b the smaller one
a-b=18
2b=3a-56
==>
a-b=18 |*(-2)
3a-2b=56
==>a=56-2*18
==>a=20 and b=a-18=2
Proof a-b=20-2=18
2=3*20-56
Numbers are 20 and 2.
