A simple way to solve fraction divided by while number problems is to multiply the denominator and the whole number together, but that only works if the numerator is 1, which in this case, they were all in fact, 1s.

Simplify the following expression

IRINA_888 [86]

Simplification of the given expression.
$\frac{a {}^{3}b {}^{2} }{a {}^{2}b }$
Divide the terms with the same base by subtracting their exponents.

$= \frac{a {}^{3 - 2} b {}^{2} }{b}$
Subtract the numbers

$= \frac{a {}^{1} b {}^{2} }{b}$
Any expression raised to the power of 1 equals itself.

$= \frac{ab {}^{2} }{b}$
Now, reduce the fraction with b.

$= ab$

A train leaves at 14.54 and arrives at its destination at 15.47. If the train travelled 66 km, what was it's average speed in km

JulijaS [17]

Answer: average speed of the train = 4,483.0 km/h

Step-by-step explanation:

Speed = Distance / Time

Distance = 66 km

Time = 15.47 cancelling 15, we have 60 sec added to 47 sec

- 14.54

= 14. 107 60 + 47

- 14. 54

53secs

53secs to hours becomes =

60 secs = 1 min

60 min= i hour

therefore 53seconds =53/3600=0.0147222hours

Speed= 66/ 0.0147222= 4,483.025

Rounding to 1 dp becomes= 4,483.0 km/h
