Answer:
approximately 72.35 minutes
Step-by-step explanation:
there are 1609.344 meters in a mile
john ran 100 meter - which would be 16.09 per mile
9.88 seconds x 16.9 = 166.97 seconds per mile
166.97 seconds x 26 miles = 4341.22 seconds
4341.22 seconds / 60 = 72.35 minutes
Divide 77.5 by 10 = 7.75
Since we divide by 10.2 (and not 10), we **subtract** 2% of 7.75, which is about 0.155 to give 7.595. (error=-0.04%)
You can also simplify a little by approximating 2% of 7.75 as 0.15 to give 7.6 as your estimate. (error=+0.026%)
exact value = 7.598...
Answer:
d=2
Step-by-step explanation:
3d + 6 = 12

divide by 3 on both sides
d=2
60 * 0.10 = 6
$6 price off
60 - 6 = $54
Solution: new price: $54
