Passenger car

Passenger car travels 1 km for 2.3 minutes, a truck during a 50 seconds long. How much is the speed of the truck less?

Result

v =  50 km/h

Solution:


x = 1/(2/3/60)
y = 1/(2/3/60+50/3600)
v = x-y

60x = 5400
3600y = 144000
v-x+y = 0

v = 50
x = 90
y = 40

Calculated by our linear equations calculator.
