1)  Speed = 12mph =12 mi/1 h =12 mi/ 60 min = 1/5 mi/ min 
1 h= 60 min
t =20 min
Distance=speed*time =1/5 *20 (mi/min *min)= 4 mi

2) If he would bike for 15 min
Distance=speed*time 
speed = distance/time = 4mi/15 min =4 mi :(1/4 h)=4*4= 16 mi/h
15 min =1/4 h

Answer:

4z4−6z3−2z2−20z+1

Step-by-step explanation:

4z5−14z4+10z3−16z2+41z−2

z−2

=

4z5−14z4+10z3−16z2+41z−2

z−2

=

(z−2)(4z4−6z3−2z2−20z+1)

z−2

=4z4−6z3−2z2−20z+1

Rewrite 1/100,000,000 as a power of 10
yarga [219]
1/100,000,000 , note that 100,000,000 = 10⁸ , then:

1/100,000,000  = 1/10⁸
Remember that 1/aⁿ  = a⁻ⁿ

Hence 1/100,000,000 = 1/10⁸ = 10⁻⁸
