Simultaneously 4369

Cars from two cities, A and B, 90 km apart, drove towards each other simultaneously. The car from city A had a constant speed of 72 km/h, and the car from city B had a speed of 90 km/h. How long and how far from city B will they meet?

Correct answer:

t =  33.3333 min
b =  50 km

Step-by-step explanation:

s=90 v1=72 v2=90 T=s/(v1+v2)=90/(72+90)=950.5556 t=60 T=60 0.5556=33.3333 min
b=v2 T=90 0.5556=50 km
