text: # Two cyclists, 112 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other, and they meet after 4 hours of riding.a. Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r to represent the speed of the slower cyclist.b. What are the speeds of the two cyclists? Put both values in the answerbox, separated with a comma, and select the appropriate units.
  
  Speed of a= 21 miles/hr
  
  r = Speed of b= 7 miles/hr
  
  Speed of a = 3r
  
  Step-by-step explanation:
  
  The cyclist are 112 miles apart
  
  Time traveled by two = 4 hours
  
  Speed of a = 3 * speed of b
  
  If a cylcles 3 times More than b, then a will cover 3*distance of b
  
  But speed = distance/time
  
  Time = 4hours
  
  Total distance=112
  
  a = 3b
  
  3b + b = 112
  
  4b = 112
  
  b = 112/4
  
  b = 28 miles
  
  a = 3b
  
  a = 3*28
  
  a = 84 Miles
  
  They bought traveled 4 hours
  
  Speed of a = 84miles/4 hours
  
  Speed of a= 21 miles/hr
  
  Speed of b = 28miles/4 hours
  
  Speed of b = 7 miles/hr
  
  The slower cyclist is traveling at a speed of 7 mph, while the faster cyclist is traveling at 21 mph.
  
  ### Explanation:
  
  We first need to recognize that the sum of the distances travelled by each cyclist is equal to the total 112 miles. We can let r represent the speed of the slower cyclist, and since the faster cyclist is traveling 3 times the speed of the slower, we can call his speed 3r.
  
  As they each traveled for 4 hours, the slower cyclist traveled a distance of 4r miles, and the faster cyclist traveled a distance of 4 × 3r = 12r miles. Their combined distances should equal the total distance between them, 112 miles. This forms the equation 4r + 12r = 112.
  
  To solve for r, we combine the like terms on the left side of the equation to get 16r = 112. Dividing both sides by 16, we find r = 7 miles per hour. Therefore, the slower cyclist is traveling at 7 mph, and the faster cyclist is traveling 3 times that speed, giving us 21 mph.
