Question

Kanye and jay wanted to see who could run faster in a minute.They both started in the same spot and ran in different directions.Their positions after running for one minute are shown on the number line

Answer 1

Kanye run faster.

Explanation:

Given that,

Time = 1 min = 60 sec

Suppose, we find the speed of kanye and Jay.

According to number line,

Kanye covers the -160m distance and Jay covers the 140 m distance.

Negative sign shows the opposite direction.

We need to calculate the speed of Kanye

Using formula of speed

`v=(d)/(t)`

Where, v = speed

d = distance

t = time

Put the value into the formula

`v=(160)/(60)`

`v=2.66\ m/s`

We need to calculate the speed of Kanye

Using formula of speed

`v=(d)/(t)`

Put the value into the formula

`v=(140)/(60)`

`v=2.33\ m/s`

The speed of kanye is more than jay.

Hence, Kanye run faster.
