Car

Car goes some distance in 3 hours and 20 minutes. If it increase speed by 10 km/h, i goes this distance in 2.5 hours. Calculate the distance.

Result

s =  100 km

Solution:


s = v * (3+20/60)
s = (v+10) * 2.5

60s-200v = 0
s-2.5v = 25

s = 100
v = 30

Calculated by our linear equations calculator.
