Step-by-step explanation:

distance divided by timr taken

Depends on units the answer needs to be in, explained below

Step-by-step explanation:

23/4=5.75 meters/minute

*60= 345 meters/ hour

From here it depends what units the answer needs to be in..

Your answer is either 345 m/hr

or 0.345 km/hr (divide by 1000 from meters)

OR 0.214 miles/ hr (if your answer needs to be empirical)

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

a is the right answer
