Percentage</h3>
Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:
Percentage = [(new value - original value) / original value] * 100%
Let x represent the new value and y represent the original value, hence:
30% = [(x - y)/y] * 100%
0.3 = (x - y)/y
x - y = 0.3y
x = 1.3y
The new value after the original value is increased by 30% is 1.3 times the original value.

Step-by-step explanation:
The speed that Morris is travelling is 0.3 ft/s
<h3>Calculating the speed of a body</h3>
Speed is the ratio of distance covered with respect to time.
Given the following parameters
Speed of Annesha = 50mi/hr
Speed of Moris = 3ft/s less than Aneesha
Convert 50mi/hr to ft/hr
50mi/hr = 73.3ft/s
Speed of Morris = 73.3 - 3
Speed of Morris =70.3 ft/s
Hence the speed that Morris is travelling is 0.3 ft/s
