Question

A car moving at a speed of 20 km per hour for 15 minutes and then at a speed of 60 km per hour for next 15 minutes . calculate the total distance covered by the car​

Answer 1

Answer:

25km

Explanation:

Moving speed of a car = 20km

Time travelled = 15minutes

Distance = 1 hour = 60minutes, 15 × 4 = 60

So, 20 ÷ 4 = 5km

Car travelled 5km in 15 minutes at the speed of 20km per hour

Moving speed of a car = 60km

Time travelled = next 15 minutes

Distance = 1 hour = 60minutes, 15 × 4 = 60

So, 60 ÷ 4 = 20km

Car travelled 20km in 15 minutes at the speed of 60km per hour

Now total car travelled in 15+15 = 30minutes is

5 + 20 = 25 km in 30 minutes

Your answer hope this will help you.
