Answer:
48 metres.
Step-by-step explanation:
How far does the cyclist travel in 3 seconds:
First, find how far the cyclist goes in 1 second:
320 metres = 20 seconds
? = 1 second
320 ÷ 20 = 16 metres
The cyclist travels 16 metres in 1 second.
How far does the cyclist travel in 3 seconds:
1 second = 16 metres
3 seconds = ?
16 × 3 = 48 metres.
The cyclist travels 48 metres in 3 seconds.
Answer:
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
Step-by-step explanation:
In order to add or subtract two fractions, a common denominator is found and then the denominators of both fractions are made equal to the common denominator.
The given fractions are:
The common denominator is the number which is the multiple off denominators of both fractions involved.
Antonio made his first error in first step. Instead of finding a common multiple denominator, he add the denominator of both fractions which is wrong.
The correct method is:
Hence,
Antonio's first error occurred in First step where he added the denominators of both fractions instead of finding a common denominator.
