Answer:
s(t) = 2t^2-3t
19 = 2t^2-3t
2t^2-3t-19=0
t = [3 +- sqrt(9-4*2*-19)]/4
t = [3 +- sqrt(161)]/4
t = [3 +- 12.6886]/4
Positive answer:
t = [3+12.6886]/4
t = 3.9221 seconds
Step-by-step explanation:
Set up an equation that models the problem:
46 * x = 423, where x is the number of lawns he needs to mow.
then x = 423/46 = 9.19
Round up to 10 lawns.
