| How much is the difference between the paths traveled by two cars in 10 s, if their speeds are equal; 1st car 10m / s 2nd car 90 km / h.
t = 10 s;
v1 = 10 m / s;
v2 = 90 km / h = (90 * 1000 m) / 3600 s = 25 m / s;
Let’s calculate the distance traveled for the first car:
S1 = v1 * t;
S1 = 10 m / s * 10 s = 100 m;
Let’s calculate the distance traveled by the second car:
S2 = v2 * t;
S2 = 25 m / s * 10 s = 250 m;
Let’s compare the paths covered by cars:
S2 / S1 = 250m / 100m = 2.5 times.
Answer: the path of the second car is 2.5 times longer than the path of the first car.
