Anis completed a journey of 4.5 km by walking for 30 minutes at a certain speed, and then by running another 25 minutes at a speed
which is 2km/h more than the walking speed. Find her walking
speed in km/h.​

speed=d/t

let him cover x distance while walking

running d=4.5-x

s1=x/0.5 km/hr(1)

s2=4.5-x//5/12(2)

atqs2=2+s1

s1=2x

s2=54-12x/5

by eqn 1 and 2

s1+s2=2x+54-12x/5

putting value of s2

s1+2+s1=2x+54-12x/5taking LCM =5

10s1+10= 10x+54-12x

as s1=2x

10s1+10= -2x+54

10s1+10=-s1+54

11s1=44

speed when walking=4km/hr

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

im not sure of the names, but the answer is 48
