Solution

The correct option is A 100 kmph
Given, time taken by car = 4 h
time taken by flight = 30 minutes = 0.5 h
distance travelled by car = 400 km
distance travelled by flight = 150 km
We know, $a v e r a g e s p e e d = \frac{t o t a l d i s t a n c e}{t o t a l t i m e}$

$∴$ $A v e r a g e s p e e d_{c a r}$ = $\frac{400}{4}$ = 100 kmph,
