the distance between Johannesburg and bloemfontein is estimated at 435km. if they travel at an average speed of 120km per hour, how long will it take them to travel from Johannesburg to bloemfontein? give answer in hours ,minutes and seconds​

3.625h,217.5min,13050sec

Step-by-step explanation:

S=vt

t=S/v

t=435/120 (km) /(km/h) =3.625h

t= 3.625*60 min = 217.5 min

t=217.5*60sec = 13050 sec

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: the answer is 110
