A high speed train travels at a speed of 300km/h. if the train sets off from a station A at 13 44 and reaches station B at 15 12

Masja [62]

Answer:

See below.

Step-by-step explanation:

The train leaves station A at 13:44 and arrives at station B at 15:12.

Which means the train took 1 hour and 28 minutes to arrive at station B.

The train travels at 300 km/h. It took at least one hour, so the answer > 300 km.

Now, the remaining 28 minutes. We divide them by 60, as there’s 60 minutes in one hour and multiply by 300, as that’s how fast the train travels per hour.

28/60*300 = 140.

300 + 140 = 440.

The distance between the stations is 440 km.

A piece of chalk is 34/56 centimeter long. Brian breaks off 23/56 centimeter long. Sara added 12/56 centimeter to the chalk that

mr Goodwill [35]

Answer:

23/56 centimeters

Step-by-step explanation:

all of the variables have a common denominator, so you can effectively ignore the denominator when solving.

1. you start off with 34/56 centimeter of chalk and Brian breaks off 23/56 centimeters worth, leaving you with 11/56 centimeters

$\frac{34}{56} -\frac{23}{56} =\frac{11}{56}$

2. Sara then added 12/56 centimeters worth, making the final amount 23/56 centimeters of chalk

$\frac{11}{56}+\frac{12}{56} =\frac{23}{56}$

An equation to summarize all of this is:

$\frac{34}{56} -\frac{23}{56} +\frac{12}{56}$
