Question

Lea walked 1/2 mile in 1/3 hour. How long will it take lea to walk 2 1/4 miles ?

Answer 1

takes her 20 minutes to walk 1/2 a mile  

2 miles=80 minutes  

1/4= 10 minutes i think  

so 80+10=1 1/2

{This is not my work!!!}

Answer 2

Step-by-step explanation:

Velocity = distance/time

1/3 h=20m

V=0.5/20=0.025m/m

So time= distance/velocity

T=2.25/0.25=90m

90m= 1.5h

I did it also by logic by using these steps:

1/2*(1/2 mile in 1/3 hour) = 1/4 mile in 1/6 hour

we have 9 quarter in 2 1/4

So 1/6 * 9 =1.5h

hope this helps !
