Detailed Solution

A car moves with a speed of

40 km / hr

for

15 \min

and then with a speed of

60 km / hr

for the next

15 \min

, the total distance covered by the car is

25 km

.
“Speed is defined as the ratio of distance covered by a body to the time taken by the body in covering that distance.” The formula of speed is given by,

Speed = \frac{Distance}{Time}

When the car moves at a speed of

40 km / hr

for

15 \min .

Speed = \frac{Distance}{Time}

\Rightarrow 40 = \frac{Distance}{(\frac{15}{60})}

\Rightarrow Distance = 40 \times (\frac{15}{60})

\Rightarrow Distance = 10 km

When the car moves at a speed of

60 km / hr

for

15 \min .

Speed = \frac{Distance}{Time}

\Rightarrow

60 = \frac{Distance}{(\frac{15}{60})}

\Rightarrow Distance = 15 km

The total distance covered by the car is equal to,
Total distance

= 10 + 15

\Rightarrow Total distance = 25 km

The total distance covered by the car is equal to

25 km
