Answer:
Hello,
le largest is <u>139</u>
Step-by-step explanation:
Since i am a lasy boy, i am going to calculate:
1+3+5+7+...+(1+2*59) there are 60 numbers
=1+3+5+..+119
=60*(1+119)/2=30*120=3600 (not enough)
4800-3600=1200 are in rest.
1200/60=20 so we add 20 to each number:
21+23+25+27+...+139=4800
3 minutes because 60 minutes = an hour so 60/20 = 3 minutes so 3 minutes per mile
8.5, since there are 2 significant digits, the only 2 numbers would be 8 and 4, so round at 4 since 5 isn't included by is above and equal to 5
