Direction 3250

The bus from Prague to M. Lázně travels at a speed of 36 km/h. At the same time, a car left Mariánské Lázně in the direction of Prague at a speed of 52 km/h. After the 90-minute journey, the two vehicles are still 30 km apart. What is the distance between the two cities?

Correct answer:

x =  162 km

Step-by-step explanation:

v1=36 km/h v2=52 km/h t1=90 min h=90:60  h=1.5 h s2=30 km  s1=(v1+v2) t1=(36+52) 1.5=132 km  x=s1+s2=132+30=162 km
