the complete question is
While driving in an exotic foreign land you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)
Step 1
<u>convert (furlongs per fortnight) to (miles per fortnight)</u>
180,000 furlongs per fortnight=180,000*(1/8)=22,500 miles per fortnight
Step 2
<u>convert miles per fortnight to miles per hour</u>
1 day=24 hour
14 day=24*14=336 hours
22,500 miles per fortnight=22,500/336=66.96 mph
therefore
<u>the answer is</u>
66.96 mph
You just need to plug in 1, 2, 3, and 4.
10*4(1)-1=39
10*4(2)-1=79
10*4(3)-1=119
10*4(4)-1=159
Angle B = 45 because 8:120 and 3:45 are equivalent proportions
