Answer:
56 mph.
B. $1.92.
Step-by-step explanation:
Mr Ford's speed = 224/4 = 56 miles per hour.
The tip = 12.80 * 0.15
= $1.92.
Part A) The rate of speed is 56 miles/ hour and
Part B) The money that waiter receive is $1.92.
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Part A:
Distance traveled by Mr.Ford = 224 miles
Time taken by Mr.Ford = 4 hours
Rate of speed can be found by
[tex]Speed = \frac{Distance}{time}[/tex]
⇒ [tex]Speed = \frac{224}{4}[/tex]
⇒ [tex]Speed = 56[/tex]
Thus the rate of speed is 56 miles/ hour
Part B:
Cost of lunch bought by Mr.Liston = $12.80
Mr.Liston gave the waiter a tip = 15%
⇒ [tex]15\% = 0.15[/tex]
Now, the money that waiter receive is
⇒ [tex]12.80(0.15)[/tex]
⇒ [tex]1.92[/tex]
Thus the money that waiter receive is $1.92.
Hence we conclude that A) the rate of speed is 56 miles/ hour and B) the money that waiter receive is $1.92.
