Answer:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.

Answer:
Step-by-step explanation:
3(-5+2x)=21
-15+6x=21 -5*3 is -15
6x=36
x=6
Add ten to both sides
Then combine the like terms
9x=81
X= 9
