Answer:
π .5 in.
Step-by-step explanation:
circumference is pi times diameter
diameter is 2 times the radius
they gave u the radius which is .25 in.
so the diameter is .25×2= .5 in.
the answer is pi times .5
A represents the speed of the aircraft.
b represents the speed of the bus.
a=2b-5
114/b=218/a
Substitution method
114/b=218/(2b-5)
(2b-5)*(114/b)= 218
(228b-570)/b = 218
228b-570= 218b
228b-218b=570
10b= 570
b=57
Plug the value of b into one of the original equations.
a=2(57)-5
a=114-5
a=109
Final answer:
Average speed of plane= 109
Average speed of bus= 57
