Question

2. Find the distance covered by a car
moving at 20m/s for 3h.​

Answer 1

Answer:

16.8 km

Step-by-step explanation:

Speed = distance/time

Distance = speed * time

Convert 20 m/s to km/h

So 20 * 5/18

             = 5.55 m/s

             = 5.6 km/h

Now Distance = speed * time

                       = 5.6 * 3

                       = 16.8 km

Answer 2

Answer :-

Given :-

• Speed = 20 m/s
• Time = 3 h

To Find :-

• Distance

Solution :-

We know that,

→ Distance = Speed × Time

Here, we are given speed and time. We first need to convert speed from m/s to km/h.

→ 1 m/s = 18 / 5 km/hr

→ 20 m/s = 20 × 18/5 = 72 km/h

Now, we have -

• Speed = 72 km/h
• Time = 3 h

Substituting the values in formula :-

→ Distance = 72 × 3

→ Distance = 216

Distance covered by car = 216 km
