Question

Last night, Shirley worked on her accounting homework for one and one half hours. During that time, she completed 6 problems. What is the velocity in problems per hour?

a. 6 per hour
b. 4 per hour
c. 10 per hour
d. 0.67 per hour
e. 15 per hour

Answer 1

option (b) is correct

Step-by-step explanation:

time t = 1 and half hour = 1.5 hour

Number of problems, n = 6

So, the velocity in problems

v = n / t

v = 6 / 1.5

v = 4

So, the rate is 4 problems per hour.

Answer 2

velocity in problems per hour = 4 per hour

so correct option is b. 4 per hour

Step-by-step explanation:

given data

worked on homework time = 1.5 hour

completed = 6 problems

to find out

What is the velocity in problems per hour

solution

we know that Shirley solve complete 6 accounting homework problem in 1.5 hour so her velocity in problems per hour will be as

velocity in problems per hour =
`(complete\ problem)/(time\ taken)` ..................1

put here value we will get

velocity in problems per hour =
`(6)/(1.5)`

velocity in problems per hour = 4 per hour

so correct option is b. 4 per hour
