Answer:
A and D
Step-by-step explanation:
Statisical questions have to deal with numbers
B is age
C is year
E is a flavor of ice cream
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:
1/5x=3/4 hour
so since 5 times 1/5=1 then
find x
multiply both sides by 5
x=15/4 hour=3 and 3/4 hour=3 hour and 45 mins
