Yes, 13 is the remainder.
See dat pic for full solution.
If the first set began to increase, than the other set tends to decrease.
The volume of a rectangular prism is L * W * H.
We are looking for whole numbers that multiply to 28.
There are 10 possible molds.

Answer:
Part 1 .
As per the given statement: In t hours the train has traveled s miles.
Distance of the train = s mile
Time = t hours
Formula for :
Speed of the train(v) =
or
mph .....[1]
Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;
Therefore, the speed of the train(v) is, 60 mph
Part 2.
Similarly,
The formula for speed of the train (v) is given by;
Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;
Therefore, the speed of the train(v) is, 90 mph
89 is the mode, it occurs the most (3 times)
89 is also the median, it is the middle number out of the 15 numbers in the data set. It there were 14 numbers you would add the two middle numbers and divide by 2 to get the median.
