Rewrite the addition problem using the GCF and the Distributive Property (Angry Birds). 25 + 100

25(1) + 25(4)

Step-by-step explanation:

25 is the greatest common factor of both 25 and 100.

If you distribute it out, 25 x 1 = 25 and 25 x 4 = 100

7.6 m/s faster

Step-by-step explanation:

Speed of swimmer = 1.8 meters per second

The distance covered by runner = 200

Time of runner = 21.3 sec

We have to find the speed of the runner first so that we can compare with the speed of swimmer.

Speed = Distance/Time

=> 200/21.3

=> 9.4 m/s

So we have to find the difference between both speeds

Difference = 9.4 - 1.8

=> 7.6 m/s

So the runner was 7.6 m/s faster..
