Answer:
44.64km/hr
Step-by-step explanation:
the length becomes (4m+20m)= 24 m in 10 sec
so speed= 2.4m/s
convert meter to km=2.4×18/5=8.64km/hr
the car and truck gng in same direction so net speed =car speed-truck speed
8.64=x-36
x=36+8.64=44.64
so car speed is 44.64
hope u understand..,if you like my explanation give me five star..
