Answer:
You already answered it.
Step-by-step explanation:
60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles
Required equation to determine two consecutive even number is
and required numbers are 4 and 6.
<u>Solution:</u>
Given that product of two consecutive positive integer is 14 more that their sum. Need to create the equation and solve it to get two numbers.
Let’s assume first even number be represented by x.
So second consecutive even number will be
Sum of two consecutive number = 
Sum of two consecutive number = 
Product of two consecutive number = 
Product of two consecutive number is 14 more that sum of two consecutive numbers, so if we subtract 14 from product, we will get sum.

One even number = 
Other even number = 
Hence required equation to determine two consecutive even number is
and required numbers are 4 and 6.
