Martin is taking a test at school. his teacher gave him 1 hour and 15 minutes to complete the test. he has been taking the test for 54 minutes. how many minutes does martin have left to finish the test?

Converting 1 hour and 15 minutes to minutes only, its 75 minutes. 75 - 54 is 21. So, Martin has 21 minutes left to finish.

Awnser:

He has 21 minutes left to complet his test

Step-By-Step:

1 hour+15 mins = 1hour and 15 mins

(60+15= 75)

1hour & 15 mins - 54 mins = 21 mins

(75-54=21)

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
