When amy roller-skates, she moves 110 yards per minute. what is her speed in miles per hour? round your answer to the nearest hundredth. (hint: 1 yd= 3 ft; 5280 ft = 1 yd.; 60 min= 1 hr)

Speed of Amy is 3.75 miles per hour.

Step-by-step explanation:

We have, speed of Amy = 110 yards per minute

This means, she covers 110 yards of distance in 1 minute.

Now, to convert the speed of Amy into miles per hour, we will first convert the distance from yards into miles and then convert time from minutes to hour.

We know that,

  1 yard = 3 feet

∴ 110 yards = 3 × 110 feet = 330 feet

Now, we also know that,

 5280 feet = 1 mile

∴ 1 feet = miles

So, 330 feet = = miles

∴ 110 yards = 330 feet = miles

Now, 60 min = 1 hr

∴ 1 min = hrs

So, 110 yards = miles and 1 min = hr

So, we can say that, Amy covers a distance of miles in

hr.

We know that,

Therefore, the speed of Amy in miles/hr is 3.75 miles/hr.
