Answer 2

Answer: After 0.34 seconds the car will be overtake the bus.

Step-by-step explanation:

Since, the speed of car = 110 km/h  = (110 × 5/18 ) m/s = 550/18 m/s

Similarly, the speed of bus = 100 km/h = 500/18 m/s

Length of car = 3 meters,

And, the length of bus = 17 meters,

Since,

$\text{The time taken by car to overtake bus} =\frac{\text{ Sum of their length}}{\text{The sum of their speed}}$

$=\frac{3+17}{550/18+500/18}$

$=\frac{20}{1050/18}$

$=\frac{360}{1050}$

$=0.342857143\approx 0.34$

Hence, after 0.34 seconds the car will be overtake the bus.
