Answer: He drove 139 miles.
Step-by-step explanation:
0.98x + 20.95= 157.17 where x is the number of miles driven.
-20.95 =-20.95
0.98x = 136.22
x= 139
Remark
This really belongs in physics. However, it can be done here. The angular velocity does not have anything to do with the length of the blade,
ω = 2π radians / time which will give you radians
ω = 2π * 45 rpm
ω = 90 π radians / minute.
This usually is expressed as radians per second
ω = 90 π / 60 radians / second
ω = 1.5 π radians / second.
