The correct answer is 10498.3.
The speed of an object is calculated when it moves from one spot to another in time interval t by dividing the distance between the two locations by the time interval. As a result of this definition, the longer it will take the object to travel the specified distance, the greater the separation between the two points.
x = x_0 + (v_x) t
In case of cheetah:
x_0 = 0;
v_c = 97.1 km/h
x = 97.1t _____(1)
In case of gazelle;
x_0 = 52.2 m = 52.2 × 10^-3 km
v_c = 79.2 km/hr
x = 52.2 × 10^-3 + 79.2t ______(2)
equating 1 and 2
52.2 × 10^-3 + 79.2t = 97.1t
52.2 × 10^-3 = 97.1t - 79.2t
52.2 × 10^-3 = 17.9t
52.2 × 10^-3×3600/17.9 = t
t = 10498.3
