Answer:
6 miles
Step-by-step explanation:
The time Johnny rode was ...
1 h 11 min = (60 min) +(11 min) = 71 min = 71 × (60 sec) = 4260 sec
The distance of one revolution of the bike tire is ...
C = πd = 3.14(30 in) = 94.2 in
So, the total distance Johnny rode was ...
(4260 sec)×(94.2 in/sec) = 401,292 in
__
We know there are 5280 feet in a mile, and each of those is 12 inches. So, the number of inches in a mile is ...
5280 ft = 5280×(12 in) = 63,360 in
__
The number of miles Johnny rode can be found by dividing the total distance by the distance in 1 mile:
(401,292 in)/(63,360 in/mile) = 6.33 mile
Johnny rode about 6 miles in 1 hour 11 minutes.
G(x) * h(x) = (4x) * (x^2-3x)
=(4x*x^2)-(4x*3x)
=4x^3-12x^2
