3. In a 100 meters race, A beat B by 10 meter or 2 seconds. What is the speed of A?

(1) 5 Km/h
(2) 10 Km/h
(3) 15 Km/h
(4) 20 Km/h

SHOW ANSWER
  Answer 4
Explanation: B can cover distance 10 M in 2 Sec
Speed of B= D/T= 10/2= 5 m/s
Total Distance= 100
Let Time by A to cover 100 m = x
Time by A to cover 100 m = x + 2
Speed of B= 5
100 = 5
X +2 100 = 5X + 10
X= 90/5 = 18
Speed of A= D/t= 100/18 m/s
In Km/h
100 x 18 = 20

4. In a `100m` race, A beats B by `20m` or 5 seconds. Find the speed of A

A 10 m/s
B 5 m/s
C 20 m/s
D 15 m/s

SHOW ANSWER
  Answer 2
Explanation: B can cover distance 20 M in 5 Sec
Speed of B= 20/5= 4 m/s
Total Distance= 100
Let Time by A to cover 100 m = x
Time by A to cover 100 m = x + 5
Speed of B= 4
100 = 4
X +5 100 = 4X + 20
X= 80/4 = 20
Speed of A= D/t= 100/20 = 5m/s
