Answer:

100 times

Step-by-step explanation:

multiples of 3 on a number cube are 3 and 6

probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3

1/3 x 300 = 100

Only answer if you are 100% sure
Hatshy [7]

Answer:

t=\frac{x}{v} = \frac{234 miles}{70 miles/h} = 3.34 h

t= 03:21 h

Step-by-step explanation:

A constant speed means that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

v =\frac{x -xo}{t-to} where x is distance and t time. The subtract is final value minus initial value

If xo=0 miles and to=0 h, then

v=\frac{x}{t}

We have distance, and speed so we need to calculate the time (how long)

t=\frac{x}{v} = \frac{234 miles}{70 miles/h} = 3.34 h

t= 03:21 h
