Un automóvil corre a 120 kilómetros por hora y otro a 80 kilómUetros por hora; si deben recorrer 960 kilómetros, ¿con cuántas ho

Artist 52 [7]

Answer:

4 hours

Step-by-step explanation:

The speed of the first car is

$v_1 = 120 km/h$

While the speed of the second car is

$v_2=80 km/h$

The time it takes for each car to cover a distance d is

$t=\frac{d}{v}$

where

d = 960 km is the total distance covered

For car 1, the time taken is:

$t_1=\frac{960}{120}=8 h$

For car 2, the time taken is:

$t_2=\frac{960}{80}=12 h$

Therefore, the difference in time is:

$\Delta t =t_2-t_1 =12 -8 = 4 h$

Cassandra cuts 5/8 inch off the top of a photo and 3/8 inch off the bottom. How much shorter is the total height of the photo no

Daniel [21]

Just add together these two fractions to determine by how much the height of the photo is shortened. 5/8 plus 3/8 comes to 8/8, or 1.

The photo is now 1 inch shorter than it was originally.
