Car is driving at 30 kilometers per hour. How far in meters does it travel in 3 seconds?
Alenkasestr [34]

Answer:

25 meters

Step-by-step explanation:

30 km/hr = (30 km/1 hr)*(1000 m/1 km)*(1 hr/60 min)*(1 min/60 sec)

30 km/hr = (30*1000*1*1)/(1*1*60*60) meters per second

30 km/hr = 8.3333333333 m/s (approximate)

----------

The speed or rate is r = 8.3333333333 meters per second approximately, and the time is t = 3 seconds, so,

distance = rate*time

d = r*t

d = 8.3333333333 * 3

d = 24.9999999999

Due to rounding error, the true answer should be d = 25. We can see this if we opted to use the fraction from of 8.3333... instead of the decimal representation which isn't a perfect exact measurement.

The formula for the perimeter of a rectangle can be expressed in more than one way. One way is P=2(l + w). Discuss how you could
ruslelena [56]
First you would divide by 2 in both sides
P/2 = l + w

Then you would subtract w from both sides
P/2 - w = l

This is the easiest method do isolate l

You can also distribute the 2 to ( l + w) first
P= 2l + 2w

Then subtract 2w from both sides
P - 2w = 2l

Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
