6 gives largest output and 12.7 or -.4 gives the smallest
Answer:
4:10 and 6:15 are equivalent to 2:5
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
Answer: 10 meters
Explanation:
29 cm : blank meters
So how do we get from 348 cm to 29 cm?
To figure this out we divide.
348 divided by 28 = 12
we divided by 12 so we do the same with 120
120 divided by 12 = 10
So that’s the answer.
I hope this makes sense and helps you :)
