two bicycle riders start from the same point and ride in opposite directions. one rider is moving twice as the other. in 3 hours, they are 72 miles apart. find the rate of each rider.​

Step-by-step explanation:

let X = speed of slow bicycle rider

2x=speed of fast bicycle rider

3(x+2x)=72

X=8mph(slowest bicycle rider)

2x=16mph(fastest bicycle rider)

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

she will travel a distance in the range of 3 - 11 miles
