Answer:

1.6.1) Inversely proportional

1.6.2) 0.6h

1.6.3) 120km

Explanation:

1.6.1)

Inversely proportional relationships are in the form of
y=k/x

y=time=t

x=speed=v

If we the relationship is inversely proportional,
must be constant for all values.

yx=k

So we just have to check the value of
in all cases.

$20*3=60\\50*1.2=60\\80*0.75=60$

Hence relation is inversely proportional.

1.6.2)

$k=60, x=100, y=k/x\\$

∴
y=60/100 ⇒
y=0.6

1.6.3)

Distance formula:

$v=s/t\\v*t=s\\s=(20*3) + (50*1.2)\\s=60 + 60\\s=120$
