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:
it is isosceles triangle with an angle = 90. Two others angle are equal. sum of all angles in triangle is 180.
2x + 90=180 --> x=45
8x+(4*30)=6(6+30)
8x+120=6x+180
2x=60
x=30 pounds of coffee
