5. A blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12

kow [346]

The average speed is 97346 feet per hour approximately

Solution:

Given that blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12 hours 22 minutes

To find: average rate of speed in feet per hour

The speed is given by formula:

$speed = \frac{distance}{time}$

From given information,

$distance = 228 \text{ miles }$

$time = 12 \text { hours } 22 \text{ minutes }$

We know that,

$1 \text{ minute } = \frac{1}{60} \text{ hour}$

Therefore,

$12 \text { hours } 22 \text{ minutes } = 12 + \frac{22}{60} \text{ hour } = 12.3667 \text{ hour }$

Substituting the values in above formula,

$\text { speed }=\frac{228}{12.3667}=18.4366$

Thus average speed is 18.4366 miles per hour

Let us convert to feet per hour

We know that,

1 mile = 5280 feet

Therefore,

18.4366 miles = 18.4366 x 5280 feet = 97345.248 feet

Thus average speed is 97346 feet per hour approximately
