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.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
