Using a stopwatch, Tyrone determines it takes him 58.2 minutes to travel 30 miles to work. The stopwatch measures to hundredths of a minute. Going by the accuracy of the stopwatch, which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?

1 mile = 5,280 feet

19.8 feet per second

19.84 feet per second

45.3 feet per second

45.36 feet per second

45.36 feet per second

Step-by-step explanation:

We know that :

Given : Distance traveled by Tyrone to work= 30 miles

Time taken =  58.2 minutes

Since , 1 mile = 5,280 feet

and 1 minute = 60 seconds

Therefore ,

Distance traveled by Tyrone to work= 5,280 x 30 feet

= 158400 feet

Time taken =  60 x 58.2 =3492 seconds

Now , Speed =

Hence, the most accurate determination for the number of feet per second Tyrone traveled on his way to work is 45.36 feet per second.
