Answer:
Jill's rate of running = 4.667 miles/hr
Step-by-step explanation:
Let's say that rate of running = x miles/hr
so rate of biking = (x + 10) miles / hr
Time of running = rate of running / distance of running = x/6
Time of biking = rate of biking/distance of biking = (x+10)/12
Total time of cycling and biking = Time of running + Time of biking
Given that total time of cycling and biking = 2 hrs
⇒ 2 = (x/6) + ((x+10)/12)
⇒ 2 = (2x+x + 10)/12
⇒ 2 × 12 = 3x + 10
⇒24 - 10 = 3x
⇒x = 14/3 =4.667 miles/hr
Hence Jill's rate of running = 4.667 miles/hr
