Link can ride his bike 20 miles into a 3 mph headwind and the same amount of time he can ride 30 miles with a 3 mph tailwind. What is Link’s biking be

Solution:

When the bike moves with the wind, the wind increases its speed and the rate is r + 3

When the bike moves against the wind, the wind decreases its speed and the rate is r - 3

The time taken is given as:

Link can ride his bike 20 miles into a 3 mph headwind and the same amount of time he can ride 30 miles with a 3 mph tailwind

Therefore,

The speed of Link bike is 15 mph

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
