Question

How long will it take a seal swimming at a speed of 8 miles per hour to travel 52 miles?

Answer 1

Hint: Speed is the quantity that relates distance and time together. Speed is the distance traveled in a particular time. When we need to know the time required to travel a particular distance, divide it by the speed and you`ll the time.

Complete step by step answer:
As we know the formula of speed is given as
\[S = \dfrac{d}{t}\]
Where s is the speed, d is the distance traveled and t is the time taken to travel the distance.
Here we are given that the seal is swimming at a speed of 8 miles per hour
She needs to travel a distance of 52 miles,
We need to calculate the time she will need to swim 52 miles,
Here as we can see that speed is given to us and the distance which needs to be covered is also given.
Now, two of the quantities are given to us and we know the relation between them so we just need to perform mathematical operations to calculate distance.
$\because S = \dfrac{d}{t}$
$ \Rightarrow t = \dfrac{d}{S}$
Given data $S = 8mh{r^{ - 1}}$and $d = 52m$$t = ?$
Substituting values
$t = \dfrac{{52}}{8}$
$t = 6.5hr$

Hence, The seal will take 6.5 hours to swim across 52 miles at a speed of 8n miles per hour.

Note:The units of the speed, time, and distance should be taken care of. Convert all the units into a single system if they are having different units. Here speed was given in miles per hour and there were no units specified for the answer so we solved for the time n hours only.
