Two cars 2

Two cars started from two positions 87 km distant at the same time in opposite directions at speeds 81 km/h and 75 km/h. What was the distance between them after 2 hours 50 minutes of driving.

Result

x =  529 km

Solution:

x=87+(81+75)⋅ (2+50/60)=529 kmx=87+(81+75) \cdot \ (2+50/60)=529 \ \text{km}
