Question

Q.11 The area of a square field is 900 m². How much time will
a girl take to run 10 times around it at the rate of 6 km/h?​

Answer 1

Answer:

• WE KNOW THAT TIME = DISTANCE\ SPEED
• HERE DISTANCE = 9OOM
• SPEED = 6KM \ HR

HERE SPEED IS IN KM\HR .. BUT DISTANCE IN M\SEC

CONVERT KM IN M = 6 X 1OOO\36OO

1.666667m\sec

TIME = DISTANCE\ SPEED

9OO\1.666667

539.999892 or almost 54O sec
