Jayden is running laps at track practice. The track is 25 kilometers around. Jayden runs 1 lap in 2 minutes. How many minutes do

givi [52]

Answer:

0.08 minutes for a kilometer.

Step-by-step explanation:

If the track is 25 kilometers, and he runs 25 kilometers in 2 minutes, he runs a kilometer in 2÷25 minutes or 0.08 minutes which is 4.8 seconds.

I'm pretty sure the track isn't 25 kilometer or he can't run a lap in 2 minutes. But if so, the answer is 0.08 minutes.

Can somewon help me plz can somewon help me

Hey there! I'm happy to help!

Let's look at our diameters.

$1*10^2^1\\5*10^2^2$

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

$\frac{5*10^2^2}{1*10^2^1} \\$

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

$\frac{5*10^2^2}{1*10^2^1} = 5*10=50$

Therefore, your answer is 50.

Have a wonderful day! :D
