Jenny peddled her bike 11 miles in 45 minutes. If she traveled at the same speed,how far would she travel in 225 minutes?
Korolek [52]

Answer:

55 miles

Step-by-step explanation:

11 miles = 45 min

speed = distance/time

speed = 11/45

speed = 0.2444 miles/min

for 225 min, speed is same

distance = speed * time

= 11/45 * 225

=55 miles

KiRa [710]
X=first week
y=second week
z=third week
t=fourth week

18 more one 2nd week than 1st
x+18=y
x=y-18

3rd week, 4 less than 2 times as second
z=2y-4

4th week, 92

ttal=382

x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92

y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78
