In t hours the train has traveled s miles. find the formula for v, the speed of the train (in mph) in terms of t and s. find the value of v when: chapter reference a t=3, s=180 plz ! part 2 in t hours the train has traveled s miles. find the formula for v, the speed of the train (in mph) in terms of t and s. find the value of v when: chapter reference b t=2.5, s=225 i will give you 20 if you can attach a

a) v = 60 mph

b) v = 90 mph

Step-by-step explanation:

Let the time be t hours and Distance be s miles. Speed = v

We know that, speed =  

v =  

Now when t =3 and s =180,

we have, v =

    v           = 60 mph

When t = 2.5 and s = 225

we have, v =

                  =

   v           = 90 mph

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

30005

yes ok
