Question

Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet

Answer 1

v = 22.5 miles/hour

Explanation:

It is given that,

The speed of Penguins is 33 ft/s.

We need to convert the speed to miles per hour.

We know that, 1 mile = 5280 feet

Speed,

`v=33\ (ft)/(s)\\\\=33* \frac{(1)/(5280)\ \text{miles}}{(1)/(3600)\ \text{hour}}\\\\=22.5\ \text{miles/hour}`

So, the speed of the Penguins is 22.5 miles/hour.
