A truck covers a distance of 640 km in 10 h. A car covers the same distance in 8 h. What is the respective ratio of the speed of the truck to that of car?


A) 3 : 4

B) 1 : 2

C) 5 : 6

D) 4:5

Correct Answer:
D) 4:5

Description for Correct answer:

Speed of truck = \( \Large \frac{640}{10} \)= 64 km/h

Speed of car = \( \Large \frac{640}{8} \) = 80 km/h

So, the required ratio = \( \Large \frac{64}{80}=\frac{4}{5} \)= 4:5
