dybincka [34]

Answer:

A

Step-by-step explanation:

Let's check each one-by-one.

THis is false.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

THis is true.

d.

We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles

So definitely 9 miles IS GREATER than 10 km.

THis is true.

So answer choice A is false, only.
