I need to know the distance.
speed= distance/ time
If you want to figure thier speed you need to divide the distance ( miles) by their time ( hours)
First you want to divide $90 by four. You want to take the answer and divide it by 2.
$90 / 4 = $22.5
22.5 / 2 = Mrs. Jackson saved $11.25.
(2)2+1=5
3(1)+1=4 is your answer
