Question

As Sara rode her bike at 13 mph, how many feet did she travel in 16 seconds? (1 mi =5280 ft)Round your answer to the nearest tenth.Do not include a unit of measure with your response; provide just a numeric answer.

Answer 1

For this case we know that the velocity is :

13 mph

And we want to find the distance in feet

The definition of the distance is given by:

D= vt

We can convert 16 second to hours and we got:

16s * (1h/ 3600s)= 1/225 hr

And then we have:

D = 13 mi/h * 1/225 hr= 13/225 mi

And then we can convert mi to ft and we got:

12/225 mi * 5280 ft/1 mi = 281.6 ft
