An object is traveling at a steady speed of 10 1/10 mi/h. How long will it take for the object to travel 1 9/10? 

First round to the nearest integer to find the estimated answer. Then find the exact answer.

I assume that 1 9/10 is MILES? If so, then:

 

1 9/10 ==19 / 10   and  10 1/10 ==101 / 10

 

[19 / 10] / [101 / 10] ==19 / 101

 

[19  / 101] x 60 minutes ==~ 11 minutes - rounded answer

 

[19 / 101] x 60 minutes ==11 minutes and 17.2277 seconds - exact answer.
