Answer 1

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..
