Answer:
2 1/3 hours or 2 hours 20 minutes.
51.4 mph to 1 decimal place.
Step-by-step explanation:
Time = distance speed
First 50 miles time taken = 50 / 60 = 5/6 hours
Second 50 miles - time = 50/40 = 5/4 hours.
Final 20 miles - time taken = 20 / 80 = 1/4 hours.
Total time taken = 5/6 + 5/4 + 1/4
= 5/6 + 6/4
= 10/12 + 18/12
= 28/12
= 7/3 or 2 1/3 hours or 2 hours 20 minutes.
Average speed = total distance / total time
= 120 / 7/3
= 120 * 3/7
= 51.4 mph to 1 decimal place.
Answer: b is the correct option
Step-by-step explanation:
Tamara earns her living as a salary plus commission employee. This means that the total amount she earns is not fixed.
Her annual salary is $48,000. There are 12 months in a year. This means
that her her monthly salary is 48000/12 = $4000
she earns 4% commission on all sales she makes.
If Tamara wants to make a total of $6,000 this month, it means that she wants to make an extra $2000($6000-$4000) this month. She can only make this from commission based on sales
Let the sales be x
4% of x = 2000
4/100 × x = 2000
0.04x = 2000
x= 2000/0.04 = $50000
Answer:
All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
