Amir ran the first 200-meter leg of the relay race with a speed of 8,260 millimeters per second. ryder ran the last 200-meter leg with an average speed of 930 centimeters per second. who ran the race faster, and how much faster was that person’s speed to the nearest meter per second

Amir is faster than Ryder by speed of 1.04 meter per second.

Step-by-step explanation:

Speed of Amir=8,260 mm per second

We know that 1m =1000mm

Convert into meter per second, divide speed by 1000

⇒ Speed of Amir=

Speed of Ryder=930 centimeters per second

We know that 1m =100 cm

Convert into meter per second, divide speed by 100

⇒Speed of Ryder=

As distance covered by both of then is same in relay race thus we can compare their speeds

We can see 8.26<9.3 and difference=9.3-8.26=1.04

∴ Amir is faster than Ryder by speed of 1.04 meter per second.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
