Step-by-step explanation:

Amount originally in the cup = amount she drank + amount remaining

= 17 * 4.5 + 148.5

= 76.5 + 148.5

= 225 milliliters.

The time she takes to drink the 148.5 mL = 148.5 / 4.5

= 33 seconds.

So time to drink it all = 17 +33 = 50 seconds.

Answer:

Therefore Josie drove 57.5 miles.

Step-by-step explanation:

Speed: The ratio of distance to time.

To find the distance we use the following formula

$Distance= time \times speed$

Given that Josie drove 45 minutes at 70 miles per hour.

$45 \ minutes= \frac{45}{60}\ h=\frac34\ h$

In 45 minutes, she traveled = $(70\times \frac34) \ miles$

=52.5 miles.

The she drove 15 minutes at 20 mile per hour.

$15 \ minutes= \frac{15}{60}\ h=\frac14\ h$

In 15 minutes, she traveled $=(20\times \frac 14) \ miles$

=5 miles

Therefore Josie drove (52.5+5) miles= 57.5 miles.
