Answer:
10.8 km per hour.
Step-by-step explanation:
Given:
Amy's home is 1.8 km from the shop.
One evening she went to the shop and was in there for 10 minutes.
Question asked:
Calculate the average speed in km/h on her way to the shop.
Solution:
Distance = 1.8 km
Time = 10 minutes
Convert it into hours
60 minutes = 1 hour
1 minute = [tex]\frac{1}{60}[/tex]
10 minutes = [tex]\frac{1}{60}\times10=\frac{10}{60}= \frac{1}{6} \ hours[/tex]
As we know:
[tex]Speed=\frac{Distance}{Time}[/tex]
[tex]=\frac{1.8}{\frac{1}{6} } \\ \\ =1.8\div\frac{1}{6} \\ \\ =1.8\times6\\ \\ =10.8\ km\ per\ hour[/tex]
Thus, the average speed on her way to the shop was 10.8 km per hour.
Answer:
The average speed on her way is 10.8 km/h
Step-by-step explanation:
Speed:
The ratio of distance to the time that takes to cover that distance is call speed of the object.
[tex]Speed=\frac{Distance}{Time}[/tex]
Amy's home is 1.8 km from the shop.
She takes 10 minutes to went the shop.
Distance = 1.8 km
Time = 10 minutes [tex]=\frac{10}{60}[/tex] h [tex]=\frac16 \ h[/tex].
The average speed on her way is
[tex]=\frac{Distance}{Time}[/tex]
[tex]=\frac{1.8\ km}{\frac{1}6 \ h}[/tex]
[tex]=\frac{1.8\times 6\ km}{ \ h}[/tex]
=10.8 km/h
