Answer 1

its c

Explanation:

Answer 2

The conversion factor used to convert kilometer per hour to meter per hour is
`1 \text{ meter } = (1)/(1000) kilometer`

Solution:

Given that average person's speed when riding a bike along a street is 18 kilometers per hour

To find: conversion factor used to convert the given speed to meters per hour

Given average speed = 18 km per hour

From the conversion parameters:

1 km = 1000 meters

or

`1 \text{ meter } = (1)/(1000) kilometer`

So, we can use the above conversion factor to convert average speed into meters per hour

18 km per hour = 18000 meter per hour

So the conversion factor used to convert kilometer per hour to meter per hour is
`1 \text{ meter } = (1)/(1000) kilometer`

Thus option C is correct. 1000 meters for 1 kilometers
