To solve this you need to make all of the percentages for the scores go back 2 decimals. For example: 82 --> 0.82
Next you multiply the decimal by the percent on the test.
0.90 × 75 = 67.5
0.95 × 10 = 9.5
0.82 × 15 = 12.3
Finally you add all of them up and get an answer.
67.5 + 9.5 + 12.3 = 89.3

Step-by-step explanation:
Answer is 44-2/5
Step by step. I did a print screen showing how we can use cancellation with the 3 and 9 so the numbers are smaller. Then we multiplied across to get 222/5.
Divide 222 by 5 = 44-4/10, simplified to 44-2/5.
First convert to miles ----------- 0.621*10=6.21
Then divide the minutes by miles.
55/6.21 = 8.86 minutes
