Answer:

Speed of second car will be 57.17 m/sec

Explanation:

We have given lead car travels = 44 laps

1 laps = 1.34 km = 1340 m

So total distance = 1340×44 = 58960 m

Speed of lead car = 55.9 m/sec

We know that $time=\frac{distance}{speed}=\frac{58960}{55.9}=1054.74sec$

As the second car is 1 lap behind so distance traveled by second car = 45×1340 = 60300 m

So speed of second car will be $speed=\frac{distance}{time }=\frac{60300}{1054.74}=57.17m/sec$
