Time taken by Priya to run 1 km = 15 × 4= 60 sec.
Time taken by Payal to run 1 km = 20 × 4 = 80 sec.
∴ Priya can give Payal a start of = 80 – 60 = 20 sec.
In 20 seconds Payal runs 250 m, so Priya can give Payal a start of 250m in one km race.
Hence, Option B is the right answer.
The total displacement travelled by ball in this case is zero.
● Note that-
1. Distance- is total length of the trajectory of an object which it travelled for a particular time with a particular or variable velocity. It is a scalar quantity.
2. Displacement- is defined as change in position of an object. It is a vector quantity.
● Hence in this case the change in position of the body is zero as the object came to its original position hence it’s displacement is zero.
● But the distance travelled by ball will be the total length of trajectory it underwent that is 20+20=40m.
