Question

Car A is travelling with a constant speed of 30 m/s and Car B is travelling with a constant speed of 110 km/h. Which car is travelling at a faster speed?

Answer 1

Car B is travelling at a faster speed

Step-by-step explanation:

We are given;

Speed of car A; V_a = 30 m/s

Speed of car B; V_b = 110 km/h

Now, V_a is already in m/s, so let's convert V_b to m/s too.

From conversions, 36 km/h = 10 m/s, therefore, 110 km/h would give;

(110 × 10)/36 = 30.56 m/s

Thus, V_b = 30.56 m/s

Comparing both speeds in m/s, we can see that 30.56 m/s > 30 m/s.

Thus, Car B is travelling at a faster speed.
