mr. johnsons travels
what is the speed at which mr. johnson is driving?
a. 7 miles per hour b. 40 miles per hour
c. 60 miles per hour d. 80 miles per hour
5 which describes the probability of tossing a number less than 1 on a number cube labeled 1-6?
a. certain
b. likely
c. unlikely
d. impossible

Explanation:

Step1: Calculate speed from graph

Speed = $\frac{\text{Distance}}{\text{Time}} = \frac{40}{1} = 40$ miles per hour

Step2: Analyze cube toss probability

A 1-6 cube has no numbers <1, so probability = 0.

Answer:

1. B. 40 miles per hour
2. D. impossible
