Ответ:
6m + 8n = - 4
6m = -8n - 4
m = -4/3n - 2/3
6m + 8n = - 4
8n = -6m - 4
n = -3/4m - 1/2
Ответ:
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..
