Question

A car travels a distance of 540 km in 3 hours. How much distance will the car travel in 21 minutes?

Answer 1

Answer:

63 Km

Step-by-step explanation:

Speed = Distance/time

          = 540/3

          = 180 Km/hr

Distance = speed x time

               = 180 x 21/60

               = 63 Km

$\large\leadsto\boxed{\rm\purple{63 \: km}}$

• Given:-

Distance travelled by car in 3 hours = 540 km

• To Find:-

Distance travelled by car in 21 minutes = ?

• Solution:-

Distance travelled by car in 3 hours = 540 km

Therefore,

✧ Distance travelled by car in 1 hour = $\\ \sf\dfrac{540}{3}km$

→ 180 km

✧ Distance travelled in 1 hour or 60 minutes is 180 km.

Therefore,

✧ Distance travelled in 1 minute = $\\ \sf\dfrac{180}{60}km$

→ 3 km

Now,

✧ Distance travelled in 21 minutes = 3 × 21 km

→ 63 km.

Therefore, the distance travelled by car in 21 minutes will be 63 km.
