Answer:
80 minutes
Step-by-step explanation:
She runs an 8 minute mile (which you can do by dividing 24/3), then how long will it take her to run 10 miles?
All you have to do from there is multiply 8x10, which gives you 80.
It'll take 80 minutes of 1:20 hours
230 is written as 2.3 × 10^2
Answer:
About 0.41 hours
Step-by-step explanation:
THe distance between Michael and Clara is 44 km.
We know D = RT,
Where
D is distance
R is rate (speed)
T is time
For Michael, we can write:
D = 47t
For Clara, we can write:
D = 61t
If we let michael's distance be x, Clara's distance would be 44 - x
So, we can say:
x = 47t
and
44 - x = 61t
Putting first equation into 2nd, we get:
44 - 47t = 61t
SOlving:
44 - 47t = 61t
44 = 61t + 47t
44 = 108t
t = 44/108 = 0.41 hours
The commute took 0.41 hours
