Distance is x a= time to go b=time back. speed* time=distance 60*a=x 45*b=x   a= x/60 b=x/45 total time = a+b= x/60+x/45= 7x/180 = 2.1 So, x = 2.1*180/7 = 54 total distance = x+x= 108 average speed = total dist/total time = 108/2.1...

probability (answer)

1.  P(htt)+ p(tht) + p(tth) = 1/8 + 1/8+1/8 = 3/8.   2.  p(f)* P(die<5) = 1/12 * 4/6 = 1/18.

need help asap (answer)

2x*.05+x*.10=9960 .2x=9960 find x then find 3x which is the total.
