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. The total distance covered by the car is:

Answer 1

Answer:

Distance = Speed × Time = (40 × 0.25) km = 10 km. Car's speed = 60 km/h. Time = 15 mins. = 0.25 hrs.

Answer 2

✨Answer :-✨

The answer should be 25 km.

Calculation:-

When the speed of the car is 40 km/h

Time taken = 15 min = 15/60 =

$Speed = \dfrac{Distance Covered}{TimeTaken}$

                                   

Distance covered d1 = speed x time taken

= 40 x 15/60 = 10 kms

$Speed= \dfrac{DistanceCoverd}{TimeTaken}$

So,

When the speed of the Car is 60 km/ h

Distance covered d2 = speed x time taken

= 60 x 15/60 = 15 kms

Hence,

Total distance covered by the car = d1 + d2

= 10 + 15

= 25 kms

∴ The answer is 25 km✅
