Answer 1

Answer:Step-by-s Amir is faster than Ryder by speed of 104 meter per second.

Answer 2

Answer: Amir is faster than Ryder by speed of 104 meter per second.

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.
