If a car is traveling at 50kph, how long would it take for the car to travel 12.5km?
Amanda [17]

Answer:

4 km

Step-by-step explanation:

T = time

D = distance

S = speed

the forumla to find the distance is

T * S = D

manipulate the equation for this problem:

D/S = T

Plug-in the known values

D = 12.5 km

S = 50kph

12.5km/50kph

cancel units and simplify

4 km

What 1 thruogh 100 added up them divided
Marina CMI [18]
We can use the sum of an aritmetic sequence
the sum from n=1 to n=r when the first term is a1 and the nth term is an is
S=\frac{n(a_1+a_n)}{2}
first term is 1
last term is 100
there are 100 terms so n=100

so the sum is S=\frac{100(1+100)}{2}
S=(50)(101)
S=5050
now you want us to divide by 10
5050/10=505


fun fact, gauss (famous math guy) did this when he was younger, legend has it that he was assigned this as an in class assigment to kill time but gauss found a neat pattern, he noticed that adding the end terms wer giving the same sum, example, 100+1=101, 2+99=101, etc, so he just needed to find al the pairs and add them all up




answer is 505
the result is 505
