If you get confused by logarithms, here's an easier way to think about this problem: What power of 2 equals 128? Well, we know 2^3 = 8, then 2^4 must equal 16. Doubling every times, we get 2^5 = 32, 2^6 = 64 and 2^7 = 128. So, the value of log₂128 is 7.
5280 ft =1 mi
hour =3600seconds 5280/3 =1760 yd= 1 mi
5yd/sec=x/3600
x=18000 yd/1760yd
x=10.227 miles
The equation is 4 + 2n= -10
