Answer:

No, she is not correct as her speed is 0.25 miles per minute.

Step-by-step explanation:

Given:

Ratio of distance  to time taken is 15 : 60.

Distance is in miles and length of time is in minutes.

We know that, average speed is given as the ratio of the distance traveled and the length of the time taken.

So, the ratio above is nothing but the average speed of Reese for cycling.

Thus, average speed of Reese is given as:

\textrm{Average speed}=\frac{Distance}{Time}\\\\\textrm{Average speed}=\frac{15}{60}\ miles\ per\ min\\\\\textrm{Average speed}=\frac{1}{4} = 0.25\ miles\ per\ min

Therefore, the average speed of Reese is 0.25 miles per minute which is not equal to the one mentioned by Reese as 4 miles per minute.

So, Reese conclusion of her average speed is incorrect. It's not 4 but the reciprocal of 4 which is 0.25 miles per minute.

Robert and Chris can skate 4 miles in 18 minutes. How far can they ride in 45 minutes?​
adell [148]

Answer: Robert and Chris can skate 10 miles in 45 minutes.

Step-by-step explanation:

Let's start by finding the unit rate.

\frac{4}{18} =\frac{2}{9} \\\frac{18}{18} =1

Robert and Chris can skate \frac{2}{9} of a mile in 1 minute. Now we can multiply both by 45 to see how far the can go in 45 minutes.

(\frac{2}{9}) (\frac{45}{1} )\\\frac{(2)(45)}{(9)(1)} \\\frac{90}{9} \\10

45x1=45

The can skate 10 miles in 45 minutes.
