ind LCM (22, 26, 351).
with speed of 18 feet per second the distance between the twins change.
<u>Step-by-step explanation:</u>
Here we have , Two twins are running away from their mother in opposite directions one with the speed of 10 feet per second and the other with the speed of 8 feet per second. We need to find How and with what speed does the distance between the twins change. Let's find out:
Two twins are running in opposite directions , Let us suppose one twin speed is denoted by , i.e. 10 feet per second
⇒
Now , Speed of other twin is , i.e. -8 feet per second . Minus sign shows the direction as this twin is moving in opposite direction :
⇒
Now, Difference in both speeds will give the change in speed between them :
⇒
⇒
Therefore , with speed of 18 feet per second the distance between the twins change.
