Vance recently ran a marathon. it took him 4.8 hours to run the 26.2 miles required to complete a marathon.
find his average speed in miles per hour. then convert his speed to feet per second. (hint: 1 mile = 5,280 feet).
(round your answers to two decimal places)
miles per hour
feet per second

8.01 ft/sec

Step-by-step explanation:

Distance = 26.2 miles

Time taken to run the distance = 4.8hrs

Average speed = ??

Average speed = distance / time

= 26.2miles /4.8hr

= 5.46 miles/hr

Convert 5.46 miles/hr to ft/sec

1 mile = 5280 ft

We have 5.46*5280 = 28828.8 ft/hr

28828.8/3600 = 8.01 ft/sec

-1/2 +2

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
