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.

if motorist drove a distance of 90km at constant speed for the first 40km and then drove 30 km/hr faster for the rest of the jou

elena55 [62]

Answer:

Step-by-step explanation:

The motorist drove at a distance of 90km at a constant speed for the first 40km, and then 20 km/hr faster for the rest of the journey.

The whole journey took him 1hr.

Let S denotes the average speed (in km/hr) for the first 40 km.

Hence we get the following relation,

40/S + (90 - 40)/(S + 20) = 1

or 50/(S + 20) = 1 - 40/S = (S - 40)/S

or (S + 20)(S - 40) = 50S or S^2 - 70S - 800 = 0 or (S - 80)(S + 10) = 0

or S = 80 (km/hr) [Ans]

[S cannot be negative value]
