Answer: A 6 hours 15 minutes
Step-by-step explanation:
Time = Distance / Speed
Time = 750 / 120
= 6.25 hours
<span>x^2-2x-3=0
(x-3)(x+1)=0 [factor]
x-3=0 [set each factor equal to zero and solve for the x-value]
x=3
and
x+1=0
x=-1
So, the solutions are x = 3 and x = -1</span>
Answer:
51 is divisible by 3
Step-by-step explanation:
51/3=17
First find the speed...
8 miles per 3 hrs
8/3 = 2 2/3 m/hr
2 2/3 m/hr × x/3 m =
2 2/3 ÷ 3 = x
8/3 ÷ 3 = x
8/3 × 1/3 = x
8/9 = x
It takes 8/9 of an hour to run 3 miles. Multiply 8/9 × 60 to find out how many minutes.
8/9 × 60 = 53.33 minutes
