To do this, You must know the formula. D=3.14l*r Or, Distance=3.14length*revolutions
3.14 is pi.
Revolutions are the turns of a wheel.
Plug in your numbers. D=3.14*20*1
D=62.8 inches
I believe that a box of 50 for $23.59 would be a better deal because 23.50 divided by 50 would equal 0.47, or in this case, 47 cents. 44.95 divided by 100 equals 0.4495, or 4495 cents. I think I'm wrong, but you can take this answer if you'd like
Answer:
450 miles per hour
Step-by-step explanation:
Kelly flies at a distance of 2,100 miles
The time taken for the trip is 4 2/3 hours
Therefore the rate of speed can be calculated as follows
= 2,100 ÷ 4 2/3
= 2,100 ÷ 14/3
= 2100 × 3/14
= 150 × 3
= 450 miles per hour
You multiply the dividend and the quotient
