Solution

The correct option is A 80 kmph
The odometer readings at Bangalore and Mumbai are 2400 and 4000 respectively.
The difference in odometer readings gives the distance travelled in km.
Distance travelled = 4000 – 2400 = 1600 km
Time taken = 20 h
We know,
$A v e r a g e s p e e d = \frac{T o t a l d i s t a n c e t r a v e l l e d}{T o t a l t i m e t a k e n}$ $= \frac{1600}{20} = 80 k m p h$
