because of this question no matter what happens

Answer 2

Answer:

70 meter per hour

Step-by-step explanation:

given ,

length of rectangular field=100m

breadth of rectangular field=75m

perimeter of rectangular field=2(l+b)=2(100+75)=2(175)=350m

The distance to be travelled by sohini for 5 times around the field is 350*5=1750m

time=quarter hour=0.25hr

speed =distance/time=1750/0.25=70mph

=70 meter per hour
