hi how are you doing today? if you ever need just tell me

step-by-step explanation:

answer:   c ?

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
