Question:

1 answer:

8 0

I think just the "possible" ones, without fully factoring, are based on factors of the last whole number-- +20.
So factors of 20: 1, 2, 4, 5, 10, 20

Answer:

54 seconds

Step-by-step explanation:

Wanda's walking rate = 3 ft/s

Wanda's head start = 27 s

Dave's walking rate= 4.5 ft/s

Let 't' be time after Dave started walking

The distance walked by Wanda and Dave, respectively, as a function of 't' are given by:

$W(t) = (27+t)*3\\D(t) = 4.5*t$

The instant 't' at which Dave catches up to Wanda (both distances walked are equal) is:

$(27+t)*3= 4.5*t\\t=\frac{81}{1.5} \\t= 54\ s$

180 - 157 = 23
