Speed of first bicyclist=x
Speed of biker= x+32
Convert 1 hour and 36 min to hours.
1+36/60 = 1.6 hours
Bicyclist time is 1.6 hours longer than biker.
Equation is:
52/x - 1.6 = 52/(x+32)
Solve for x.
52(x+32)-1.6(x+32)=52x
5x+1664-1.6x²-51.2x=52x
Simplify
1.6x²+51.2x-1664=0
Using quadratic formula.
We get
x=20 km per hour which is the speed of the Bicyclist.
Now speed of biker= 20+32=52 km/hr
Answer: Speed of Bicyclist= 20 km/hr
