Round 0.687 yo the nearest tenths place
Vaselesa [24]

Answer: 0.7

Locate the tenths place which is just to the right of the decimal point. We see a 6 in this spot. Just to the right of this 6 is the value 8. Since 8 is larger than 5, we bump the 6 up to 7 and erase everything else to the right. You can think of it like this

0.687 ---> 0.6 which bumps up to 0.7

This is like saying 687 is closer to 700 than it is to 600

What is the unit rate for meters per second if a car travels 238 meters in 17 seconds?
madreJ [45]
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
