Answer:
Adverage of 20 mph
30 1/5 = 30.2
2/3 = .6667
30.2 x .6667 = 20.13
Answer:
45.3 miles/hour
Step-by-step explanation:
the information we have is:
distance:
[tex]d=30\frac{1}{5}miles=30.2miles[/tex]
time:
[tex]t=\frac{2}{3} hour[/tex]
the formula for the average speed is:
[tex]v=\frac{distance}{time} =\frac{d}{t}[/tex]
substituting all the known values we get:
[tex]v=\frac{30.2miles}{2/3hour} =\frac{3(30.2miles)}{2hour}= 45.3miles/hour[/tex]
the average speed in miles per hour is: 45.3
