Read Solution (Total 4)
-
- A can complete a race of 2km in 260sec
Time diff b/w A & B is 4min34sec-4min20sec => 14 sec
A => 2000m => 260sec
x => 14sec
=> x = 2000*14/260 =>107.6mts

- so,A can travel in 260sec a distance of 2km.
in additional (4min34sec-4min20sec)=14sec he can travel...
2*14/260=.107km
so in the meanwhile A can travel 2107meters. - 11 years agoHelpfull: Yes(8) No(7)
- 107.6 mtrs..................................................

- time taken by A=260sec
time taken by B=274sec
A reaches 274-260=14sec before B;
SO extra distance covered by A is given by
speed of A*time(14 sec)
(2000m/260s)*14s=107.69230m - 11 years agoHelpfull: Yes(1) No(0)
