Answer:
2(5)+5(0)=10
Step-by-step explanation:
There are several ways for this equation to work but a very simple way is shown below.
2*510+5*0=10
10+0=10
10=10
y2 = y , x2 = 5
y1 = 2 , x1 = 3
-4 = y-2 ==> y = -2
His average speed is 634/13 = 48,77 miles/hour. Well, he's fast :D
0.192 = 24/125
0.042 = 21/500
189/1000 = 0.189
3/1000 = 0.003
