Answer:
Total Distance covered = 25km.
Step-by-step explanation:
Given: Car travells with a speed of 40km/hr for the first trip of 15 minutes.
and then it travels with a speed of 60km/hr for rest 15minutes.
We kno that, Distance covered is product of Speed and Time.
Distance covered = Speed × Time
So, let's find the distance covered in the first trip of 15 minutes whn the speed of car was 40 km/hr.
1 hr = \sf \dfrac{15}{60}
60
15
\sf Distance = 40 \times \dfrac{15}{60}Distance=40×
60
15
\bf Distance = 10kmDistance=10km
Now, let's find the distance covered in the second trip of 15 minutes where speed was 60km/hr.
\sf Distance = 60 \times \dfrac{15}{60}Distance=60×
60
15
\bf Distance = 15kmDistance=15km
Total Distance Covered = 10 km + 15 km
=> 25km
