Answer:
Step-by-step explanation:
560 miles
----------------------- = 11 bikers who ride 50 miles each, plus one more biker,
50 miles/biker who rides only 10 miles (from 550 to 560 miles)
In a team bike race, a biker must ride exact 50 miles.
If they need to achieve 560 miles, the number of bikers should be a positive integer (b) which is equal or larger than: 560/50 = 11.2. => The answer should be b > 11 or b>=12.
Hope this helps!
