At what time and at what distance the van catch up with the truck. WORD PROBLEM ON MOVEMENT.

Result

s =  56.25 km
T = 9:45 hh:mm Wrong answer

Step-by-step explanation:


s = 45•(t-8.5)
s = 75•(t-9.00)

s-45t = -382.5
s-75t = -675

s = 225/4 = 56.25
t = 39/4 = 9.75

Our linear equations calculator calculates it.
T=t=9.75=439=9.75=9:45 hh:mm
