Use the following unit fractions to express 180 miles per hour in feet per second
5280 ft/ 1 mi, 60 min/ 1 hr , and 60 sec/1 min
Problem:
180 mi/hr=blank ft/sec

264 ft/sec

Step-by-step explanation:

We need to use the conversion factors

5280 ft/ 1 mi, 60 min/ 1 hr , and 60 sec/1 min

180 miles         1 hour               1 min        5280 ft

*  * *

hour                60 minutes       60 sec      1 miles

The hours, minutes and miles cancel are we are left with ft/sec

180 *5280        ft

*  

60*60                 sec      

264 ft/sec

264 ft/sec

Step-by-step explanation:

180 miles / hour

(180×5280) ÷ (1×60×60)

950400 ÷ 3600

264 ft/sec

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
