Answer:
[tex]5\frac{miles}{hour}[/tex]
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x-----> the distance in miles
y-----> the time in hours
s----> the speed in mph
so
[tex]s=\frac{x}{y}[/tex]
we have
[tex]x=1/4\ miles[/tex]
[tex]y=1/20\ hour[/tex]
substitute
[tex]s=\frac{(1/4)}{(1/20)}=5\frac{miles}{hour}[/tex]
Answer : The Elena’s running speed is, 5 mile/hour
Step-by-step explanation :
Speed : It is defined as the rate at which an object moves with respect to time.
To calculate the time taken for the given speed, we use the equation:
[tex]s=\frac{d}{t}[/tex]
where,
s = speed = ?
d = distance traveled = [tex]\frac{1}{4}miles[/tex]
t = time taken = [tex]\frac{1}{20}hour[/tex]
Putting values in above equation, we get:
[tex]s=\frac{(\frac{1}{4}miles)}{(\frac{1}{20}hour)}\\\\s=\frac{20}{4}miles/hour\\\\s=5mile/hour[/tex]
Hence, the Elena’s running speed is, 5 mile/hour
