Question

What is the rate and unit rate of 40 meters in 16 seconds?

Answer 1

Unit rate is `2 1/2` meters per second.

Explanation:

As the object involved in `16` second covers `40` meters

in `1` second it will cover `40/16` in each second which is equal to

= `(2xx2xx2xx5)/(2xx2xx2xx2)`

= `(cancel2xxcancel2xxcancel2xx5)/(cancel2xxcancel2xx2xx2)`

= `5/2=(2xx2+1)/2=(2xx2)/2+1/2=2 1/2`

Hence, unit rate is `2 1/2` meters per second.
