Cristofer · Answer 1

Number of bikers: b

miles ridden by each biker: 50

number of miles ridden by the team: 50b

Condition: 50b ≥ 560

=> b ≥ 560 / 50

=> b ≥ 11,2

Given that b refers no number of persons it has to b an integer and b has to be at least 12

=> b ≥ 12.

If there would be 11 bikers the team only could complete 11*50 = 550 miles, so they cannot complete the required 560 miles.

Answer: b ≥ 12
