Answer 1

AREA TO BE PLOUGHED = 60-12=48 ACRES

TOTAL DISTANCE=X

SO 160KM=1/4 OF X

X=160*4

X=640 KM

Answer 2

Answer:

151.

TOTAL LAND = 60 ACRES

PLOUGHED LAND= 12 ACRES

UNPLOUGHED LAND = 60- 12=48 ACRES.

152.

SPEED OF CAR= 80 KM/HR

TIME TAKEN=2 HRS.

DISTANCE=  SPEED *TIME

  =80*2

 =160KM

BUT THIS IS THE SPEED WHICH WILL BE COVERED IN  2 HRS AND ALSO 1/4 OF THE DISTANCE

SO THE TOTAL DISTANCE WILL BE =160*4=640 KM

I HOPE THIS WILL HELP U A LOT,
