Answer:
Hichman will walk faster.
Step-by-step explanation:
Hichman walks 84 feet in 7 seconds and Brittany walks 110 feet in 20 Second.
We need to say who walks faster.
For Hichman,
Distance, d = 84 feet and time, t = 7 s
Speed,
![v_H=\dfrac{d}{t}\\\\v_H=\dfrac{84}{7}\\\\=12\ ft/s](https://tex.z-dn.net/?f=v_H%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv_H%3D%5Cdfrac%7B84%7D%7B7%7D%5C%5C%5C%5C%3D12%5C%20ft%2Fs)
For Brittany,
Distance, d = 110 feet and time, t = 20 s
Speed,
![v_B=\dfrac{d}{t}\\\\v_B=\dfrac{110}{20}\\\\=5.5\ ft/s](https://tex.z-dn.net/?f=v_B%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv_B%3D%5Cdfrac%7B110%7D%7B20%7D%5C%5C%5C%5C%3D5.5%5C%20ft%2Fs)
It can be seen that speed of Hichman is 12 ft/s and the speed of Brittany is 5.5 ft/s. It is clear that the speed of Hichman is more than that of Brittany. Hence, Hichman will walk faster.
