PLEASE HELP ASAP


Jackson digs a hole at a rate of 3/5 feet every 10 minutes. After digging for 40 minutes, Jackson places a plant in the hole that fills exactly 9/10 feet of the hole.

Relative to ground level, what is the elevation of the hole after placing the plant in the hole?

Respuesta :

Make the 3/5 into 6/10 6 times 4 is 24. So you dug 24/10 of a foot down. Then subtract 9/10
15/10 feet down is the answer.
It could be simple if used down to 3/2 or 1(1/2)
