find his average speed in kilometers per hour.

Or, as a mixed number

Step-by-step explanation:

The question is

Harvey runs 3 1/6 km in 1/4 hours. What's his average speed in km per hour?

To find the average speed in km per hour, we have to divide the kilometers by the hours. However, we first need to transform each mixed number into a fraction, as follows

Then, we divide

Therefore, the average speed in kilometers per hour is

Or, as a mixed number

d. vertex

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
