Simone travels 90 miles at an average speed of 40 mph.
denis-greek [22]

Using the relation between velocity, distance and time, it is found that her average speed for the final 30 miles is of 55.56 mph.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is distance divided by time, that is:

v = \frac{d}{t}

Simone travels 90 miles at an average speed of 40 mph, hence the time is given by:

t_1 = \frac{90}{40} = 2.25

She then travels a further 30 miles, with an average speed for the journey of 43 mph. Hence, she traveled 90 + 30 = 120 miles, and the total time is given by:

t = \frac{120}{43} = 2.79

Hence, in the second part, she traveled 30 miles in 2.79 - 2.25 = 0.54 hours, so the velocity is given by:

v = \frac{d}{t} = \frac{30}{0.54} = 55.56

Her average speed for the final 30 miles is of 55.56 mph.

nalin [4]
Since she bought 4 bags of 50 beads and 3 bags of 200 beads you only need to use two operations: multiply and add. 4 x 50 is 200 3 x 200 is 600 600 + 200 = 800 Mariah purchase 800 beads in total.
