Answer:
1/64
Step-by-step explanation:
Rewrite the expression using the negative exponent rule b⁻n = 1/bⁿ.
1/16³/²
simplify the denominator
rewrite 16 as 4²
1/(4²)³/²
Apply the power rule and multiply exponents, (aⁿ)ᵃ=aⁿᵃ
1/4²(³/²)
Cancel the common factor of 2
Cancel the common factor
then rewrite the expression
1/4³
Raise 4 to the power of 3
1/64
The two trains will meet when the sum of the distances covered by the two trains is 504 miles.
distance = speed x time.
Let the time covered when they meet be x, then:
80x + 100x = 504
180x = 504
x = 504/180 = 2.8.
Therefore, the two trains will meet in 2 hours 48 mins.
