A car will depart from place A at 1 PM at a speed of 72 km/h. At the same time, a truck speeds up 68 km/h from point B, which is 315 km away from point A. When and where will they meet?

Result

t = 15:15 hh:mm Wrong answer
s1 =  162 km

Step-by-step explanation:

s1+s2=s v1=72 km/h v2=68 km/h s=315 km  v1 x+v2 x=s 72 x+68 x=315  140x=315  x=140315=2.25  x=49=2.25  t=x+13.00=2.25+13.00=15.25=15:15 hh:mm
s1=v1 x=72 2.25=162 km
