Show Answer
Answer:
Correct Answer: E
Solution:
- $ \because $ Distance covered by truck = 640 km and time taken = 10 h
$ \therefore $ Speed of truck $ =\frac{640}{10}=64,km/h $ Distance travelled by car = 640 km and time taken = 8 h
$ \therefore $ Speed of car $ =\frac{640}{8}=80,km/h $ Hence, required ratio = 64: 80 = 4: 5
