if it take someone 55 seconds to travel one mile, how fast are they traveling

Sagot :

Answer:

estimate: around 60mph

actual: 65 mph

Step-by-step explanation:

estimate: rounded 55 to 60 so 1 minute=1 mile then multiply both by 60 (bc there is 60 minutes in an hour) the get 1 hour=60 miles, so the estimate is 60mph

actual: 55 seconds=1 mile so divide 60 by 55 seconds to get about 65 miles per hour

Answer:

~65.45mph  (65.454545...mph)

Step-by-step explanation:

[tex]55(seconds) = 1 (miles)[/tex]

[tex]55(seconds) * 60 = 1 (miles) * 60[/tex]   ⇒    [tex]55(minutes) = 60 (miles)[/tex]

[tex]55(minutes) * 60 = 60 (miles) * 60[/tex]   ⇒  [tex]55(hours) = 3600 (miles)[/tex]

3600(miles)/55(hours ≈ 65.45mph
