Two cyclists start at the same point and travel in opposite directions. one cyclist travels 8 kmh slower than the other. if the two cyclists are 176 kilometers apart after 4 hours, what is the rate of each cyclist?

rate of slower cyclist=18 km/h

rate of faster cyclist=26 km/hr

Step-by-step explanation:

let the rate of the slower cyclist= x

and the rate of the fastest cyclist will be= x+8

so according to conditions the distance time is 4 hours so multiply both by 4

distance=travel time  x rate of travel  

..

4x+4(x+8)=176

4x+4x+32=176

8x=176-32

8x=144

X= 144/8= 18

x+8= 18+8=26

rate of slower cyclist=18 km/h

rate of faster cyclist=26 km/hr

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
