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. Abhays speed is:
5 kmph
6 kmph
6.25 kmph
7.5 kmph
Explanation:
Let Abhays speed be $ x $ km/hr.
| Then,$ \dfrac{30}{x} $-$ \dfrac{30}{2x} $= 3 |
$\Rightarrow$ 6$ x $ = 30
$\Rightarrow x $ = 5 km/hr.
