Agroup of hikers walked 2 1/4 km in 3/4 hour. the distance here varies directly with time. what is the constant of variation?

k = 3

let distance walked be d and time be t

since distance varies directly with time then

d = kt ← k is the constant of variation

k =

note that 2 = , hence

k = / = 3

the axial of symmetry

step-by-step explanation:

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10
