Solution:
Let the speed of cyclist without any wind = x miles per hour
Speed of cyclist when speed of wind increases by 2 miles per hour = (x + 2 )miles per hour
Also , relation that is given between speed of cyclist without wind and with wind is :Riding with the wind at her back, a cyclist takes an hour less time to cover 80 miles than without any wind.
Converting this statement into terms of equation:
→→→To solve the Quadratic equation of type : a x² + b x + c=0, I have used discriminant method, to find the roots, which is x=
Speed of cyclist without wind = 11.68 miles per hour
Speed of cyclist when wind is flowing = 11.68 +2 = 13.68 miles per hour
Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm
