A moving platform moves with a speed of 100 km/hr. What will be the speed of a boy who is running on it with a speed of 10 km/hr along the motion of the moving track measured by a speed sensor placed on stationary ground?

A moving platform moves with a speed of 100 km/hr. What will be the speed of a boy who is running on it with a speed of 10 km/hr along the motion of the moving track measured by a speed sensor placed on stationary ground? Correct Answer 110 km/hr

Speed of the boy measured by a speed sensor who is running on the moving platform will be 110 km/hr. Since both move in the same direction then the speed of the boy gets added up with the speed of the moving platform therefore net speed becomes 100+10=110.

Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy, we get the age of the father of the younger boy. Similarly, we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger than his father by 3 years. Then, what are the ages of elder and younger boys ?
