What was the total distance, in miles, Eil has biked when he finally reached the library?

MrMuchimi

Answer:

Distance covered by Eli is $5\frac{19}{20}$ miles.

Step-by-step explanation:

Eli biked the distance from his home initially = $1\frac{1}{10}$ miles

Then he remembered that he had left a book at home.

He came back home and traveled the distance = $1\frac{1}{10}$ miles

Then he reached the library by traveling the distance = $3\frac{3}{4}$ miles

Total distance covered by him = $1\frac{1}{10}+1\frac{1}{10}+3\frac{3}{4}$

= $1 + \frac{1}{10}+1+\frac{1}{10}+3+\frac{3}{4}$

= 5 + $\frac{1}{10}+\frac{1}{10}+\frac{3}{4}$

= $5+\frac{2}{20}+\frac{2}{20}+\frac{15}{20}$

= $5+\frac{19}{20}$

= $5\frac{19}{20}$ miles

Therefore, distance covered by Eli is $5\frac{19}{20}$ miles.

Elke lives mile from 1/10school. Haresh lives 2/3 mile from school.

lawyer [7]

Answer: 17/30

Step-by-step explanation:

From the question, Elke lives 1/10 mile from school while Haresh lives 2/3 mile from school.

The closer to school Elke is than Haresh will be:

= 2/3 - 1/10

We can change the fractions to have thesame denominator which will be:

= 2/3 - 1/10

= 20/30 - 3/30

= 17/30

The distance between them is 17/30 miles
