In covering a distance of 30 km, Abhay takes 2 hours more than Sameer. If Abhay doubles his speed, then he would take 1 hour less than Sameer. Abhay s speed is:
5 kmph
6 kmph
6.25 kmph
7.5 kmph
Explanation:
Let Abhay s speed be x km/hr.
Then,$\dfrac{30}{x}-\dfrac{30}{2x}$=3
$\Rightarrow $6x = 30
$\Rightarrow$ x = 5 km/hr.
Let Abhay s speed be x km/hr.
Then,$\dfrac{30}{x}-\dfrac{30}{2x}$=3
$\Rightarrow $6x = 30
$\Rightarrow$ x = 5 km/hr.
