Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{❥︎sᴏʟᴜᴛɪᴏɴ ࿐}}}}}}$

⇏Speed of a car in first 15 minutes = 40 km /h

⇏Distance covered = Speed × time taken

⇏60 minutes = 1 hour

⇏15 minutes = 15/60 hour.

⇏Distance covered = 240 × 15/ 60 = 10 km.

⇏Speed of a car in next 15 minutes = 60 km/h

⇏Distance covered = 69 × 15/ 60 = 15 km.

Total distance covered = (10+15) = 25 km.

★Total distance covered by the car is 25 km.★

Hope it helps ✦

Answer 2

Question :-

A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60km/h for the next 15 minute the total distance covered by the car is?

Required Answer :-

Total distance covered by the car is 25km.

Given :-

Speed of car in first 15 minutes = 40km/hr

Speed of car in next 15 minutes = 60km/hr

To find :-

Distance covered by the Car

Formula used :-

Distance covered = speed × time

Solution :-

Speed of car in first 15 minutes = 40km/hr.

(convert 15 minutes into hour)

60 minutes = 1 hour

15 minutes = 15/60 hour

Distance covered = speed × time

= 40 × 15/60

= 10km

Speed of car in next 15 minutes = 60km/h

15 minutes = 15/60 hour

Distance covered = speed × time

= 60 × 15/60

= 15km

Total distance covered = Distance covered in first 15 minutes + Distance covered in next 15 minutes

10 km + 15 km = 25km

Therefore, total distance covered by car is 25km.
