Train expres

At 8.00 strarted from Bratislava to Poprad express Tatry. Cities are distant 340 kilometers. At the same time started from Poprad express Danube to Bratislava. Express Tatry's average speed is 80 km/h, Danube 90 km/h. At what distance from Poprad trains will meet?

Result

x =  180 km

Solution:


80t + 90t = 340
x = 90t

170t = 340
90t-x = 0

t = 2
x = 180

Calculated by our linear equations calculator.
