A dolphin can swim up to 40 miles per hour. What is this speed in feet per minute

vitfil [10]

Hey there!

A dolphin swims 40 miles per hour. In feet, this is 211,200 because there’s 5,280 feet in a mile. Divide 211,200 by 60 to get 3,520. The dolphin travels 3520 feet a minute.

I hope this helps!

A truck with 36-in.-diameter wheels is traveling at 55 mi/h.

kkurt [141]

Answer:

The angular speed is 3,227 rad/min

Step-by-step explanation:

Remember that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

The circumference is equal to

$C=\pi D$

we have

$D=36\ in$

substitute

$C=\pi (36)$

$C=36\pi\ in$

step 2

we know that

The speed of the wheel is 55 mi/h

Convert to mi/min

55 mi/h=55/60 mi/min

Convert to in/min

(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min

we know that

The circumference of the wheel subtends a central angle of 2π radians

using proportion

Find out how much radians are 58,080 inches

$\frac{36\pi }{2\pi }=\frac{58,080}{x} \\\\x=2*58,080/36\\\\x=3,226.67 \ rad$

therefore

The angular speed is 3,227 rad/min
