Amanda has 60 minutes to complete 35 math problems. she has already completed 20 math problems in 30 minutes. how much longer will it take for her to finish the last 15 math problems. write an inequality and solve

The time take for her to finish the last 15 problems = 1.5 × 15

                                                               = 22.5 minutes

Step-by-step explanation:

The number of math problems complete in 60 minutes = 35

the number of math problems completed in 30 minutes = 20

therefore no. of math problems completed in 1 min = 20 ÷ 30

                            =  

                              = 1.5

The time take for her to finish the last 15 problems = 1.5 × 15

                                                               = 22.5 minutes

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
