Question

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

Answer 1

Distance covered by Eli is
`5(19)/(20)` miles.

Explanation:

Eli biked the distance from his home initially =
`1(1)/(10)` miles

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

He came back home and traveled the distance =
`1(1)/(10)` miles

Then he reached the library by traveling the distance =
`3(3)/(4)` miles

Total distance covered by him =
`1(1)/(10)+1(1)/(10)+3(3)/(4)`

=
`1 + (1)/(10)+1+(1)/(10)+3+(3)/(4)`

= 5 +
`(1)/(10)+(1)/(10)+(3)/(4)`

=
`5+(2)/(20)+(2)/(20)+(15)/(20)`

=
`5+(19)/(20)`

=
`5(19)/(20)` miles

Therefore, distance covered by Eli is
`5(19)/(20)` miles.
