<u>First Train:</u>
Time taken = 9 hours (2pm to 11pm)
Let the speed be x
Distance = Time x Speed = 9x
<u>Second Train:</u>
Time taken = 5 hours (6pm to 11pm)
Speed = x + 48
Distance = Time x Speed = 5(x + 48)
Since both the distance they traveled are the same, we equate the distance to solve for x.
<u>Solve for x:</u>
9x = 5(x + 48)
9x = 5x + 240
4x = 240
x = 60
<u>Find the speed:</u>
x = 60 mph
x + 48= 108 mph
Answer: The spend of the two trains are 60 mph and 108 mph.
Answer:
Vales of a =3 and b = 6
Step-by-step explanation:
Given that: .....[1] where a and b are positive integers
we can write 81 and 24 as;
We have [1] as;
Using power rules;
which implies a = b
then;
On comparing both sides we have;
a = 3 and
⇒
Therefore, the value of a and b are, 3 and 6
