Answer:
1:10 pm
Step-by-step explanation:
<em>60 minutes in an hour</em>, so
8:50am + <u>4 hours</u> = 12:50pm
12:50pm + <u>20 minutes</u> = 1:10pm
Step-by-step explanation:
The mean is the average. Add up all the points, then divide by the number of points.
(12 + 17 + 11 + 13 + 17 + 15) / 6 = 14⅙
It is easier to compare a positive number and a negative number because it’s just like regular adding
I assume a unit rate is simply ms^-1 or whatever.
In order to determine m/s one must make the "per whatever" part equal to 1. In this case it is seconds, so we must make seconds equal to 1.
If in 17 seconds it travels 238 metres, that means in 1 second it travels 238/17m=14m
Therefore the unit rate (speed) of the car is 14m/s or 14ms^-1
