Question

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

Answer 1

like a first step convert 58,2 minutes in second and convert the 30 miles in feet

suppose you will get T seconds for 58,2 minutes and Y feet for 30 miles

to get the correct answer you can us the rule of 3 simple

in T seconds travel Y feet
in 1 sec. travel x feet

x = (1*Y)/T = ? feet/sec.
