A gives a start of 50m to B and finished a race of 1 km in dead heat. Find the ratio of their speed.

10 : 9 20 : 19 3 : 2 21 : 19

20 : 19

A                              B Distance         1000m                      950               ⇒         20           :             19 When time is same, then speed is directly proportional to distance. Therefore,  Ratio of speed ⇒ 20           :             19
