Answer:
a = 3
b= -1
c = 5
X = (-b +- sqrt [b^2 - 4ac]) / 2a
X = (--1 +- sqrt (1 - 4*3 * 5)) / 2* 3
x = (1 += sqrt (1 -60)) / 6
x1 = (1 + sqrt (-59)) / 6
x2 = (1 - sqrt (-59)) / 6

Step-by-step explanation:
A) Possible outcomes are ...
(1, 3), (1, 4), (2, 2), (2, 3), (3, 1), (3, 2), (4, 1)
for a total of 7 out of 36 outcomes that match your requirements.
p(3 < sum ≤ 5) = 7/36
B) Possible outcomes are ...
(6, 1), (6, 3), (6, 5), (1, 6), (3, 6), (5, 6)
for a total of 6 out of 36 outcomes that match your requirements.
p(6 and odd) = 6/36 = 1/6
The distance is 20 speed 58 =h
20×58 in 1 hour =1160
