The speed of a car is 63 km/h. What is the distance travelled by it in 10 seconds?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 175 m.
Distance = Speed × Time
According to the given question,

Speed of car in m/sec = 63 × 5/18 = 17.5 m/sec
Now, distance = 17.5 × 10 = 175 m
