Question

1 numeric 1 point todd drives to work-55 miles one way- in 1.4 hours. what is his average velocity? answer 2 numeric 1 point how much time does it take for a bird, flying at a velocity of 45 miles per hour, to ravel a distance of 1,800 miles? answer 3 numeric 1 point what is the velocity of a penguin that swims 90 meters through the water in 12 minutes? answer

Explanation:

Question 1

Step1: Recall velocity formula

The formula for average velocity \( v \) is \( v=\frac{d}{t} \), where \( d \) is distance and \( t \) is time.

Step2: Substitute values

Given \( d = 55 \) miles and \( t=1.4 \) hours. So \( v=\frac{55}{1.4}\approx39.29 \) miles per hour.

Step1: Recall time formula

From \( v = \frac{d}{t} \), we can rearrange to \( t=\frac{d}{v} \).

Step2: Substitute values

Given \( d = 1800 \) miles and \( v = 45 \) miles per hour. So \( t=\frac{1800}{45}=40 \) hours.

Step1: Recall velocity formula

\( v=\frac{d}{t} \), first convert time to hours or keep in minutes. Let's use minutes. \( d = 90 \) meters, \( t = 12 \) minutes.

Step2: Calculate velocity

\( v=\frac{90}{12}=7.5 \) meters per minute. If we want in meters per hour, \( 7.5\times60 = 450 \) meters per hour, but the question doesn't specify units for velocity, so using minutes: \( v = 7.5 \) m/min.

Answer:

\( \approx39.29 \) miles per hour
