How long would it take to travel 425 m at the rate of 50 m/sm/s ?
2 answers:
Answer:
8.5 s
Step-by-step explanation:
How long means time taken, so to find the time taken to travel 425 m at the rate of 50 m/s, we will simply use the formula below
V =
where v is the speed or velocity, d is the distance travelled and t is the time taken.
From the question given, distance (d) = 425 m, velocity/speed(v) = 50
We can now proceed to insert our values into the equation
V =
50 =
Cross -multiply
50 t = 425
Divide both-side of the equation by 50
=
(On the left-hand side of the equation 50 at the numeartor will cancel-out 50 at the denominator leaving us with just x, while on the right-hand side of the equation 425 will be divided by 50)
t = 8.5 sec.
Therefore the time taken is 8.5 s

Answer:
Students on Honor Roll had no advantage to get the Science class requested. It was a fair class assignment. In fact No Honor Roll students had advantage over honor Roll Students in obtaining Science Class as requested.
Step-by-step explanation:
Here let us streamline the information we are given one by one
1.) Honor Roll
Get Requested Science Class : 64
Did Not get Requested Science Class : 80
Total : 144
Percentage of Honor Roll Students getting Science class as requested =
= 44.44%
2.) No Honor Roll
Get Requested Science Class : 315
Did Not get Requested Science Class : 41
Total : 356
Percentage of Non Honor Roll Students getting Science class as requested
= 88.8%
By observing the above result , we can assume that Honor Roll students did not have any advantage over non Honor Roll students in getting Science Class as they requested.
