Question

A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. Calculate the total distance covered by the car.​

Answer 1

Answer:

Car's speed = 40 km/h

Time = 15 mins. = 0.25 hrs.

Distance = Speed × Time = (40 × 0.25) km = 10 km.

Car's speed = 60 km/h.

Time = 15 mins. = 0.25 hrs.

Distance = Speed × Time = (60 × 0.25) km = 15 km.

So, Total distance travelled = (10+15) km = 25 km

Answer 2

Answer ::

The total distance covered by car is 25km.

Step-by-step explanation ::

To Find :-

• The total distance covered by the car

Solution :-

Given that,

• A car moves with a speed of 40 km/h for 15 minutes
• Then, again with a speed of 60 km/h for the next 15 minutes

ACCORDING THE QUESTION,

• The total distance covered by the car is,

As given time taken by the car, is on minutes, so we need to convert it on seconds,

➳ 15 minutes = 0.5 hours

Now, the distance covered is,

As we know that,

Distance = Speed × Time,

• Distance covered on first 0.5 hours,

➳ Distance = 40 × 0.5

➳ Distance = 10km

Distance covered on other 0.5 hours is 10km/h.

• Distance covered on other 0.5 hours,

➳ Distance = 60 × 0.5

➳ Distance = 15km

Distance covered on other 0.5 hours is 15km/h.

Therefore, the total distance covered by car is,

➳ ( 10km + 15km )

➳ 25km

The total distance covered by car is 25km.
