$\: \: \: \: \:$

For the first part of the journey :-

$\: \: \: \: \: \:$

Speed = 60 km / h ;

Time = 15 min = 1 / 4 hour

$\: \: \: \: \:$

$\large \rm \green{ Speed \ = \frac{Distance} {Time} }$

$\: \: \: \: \:$

60 km / h = Distance / 1 / 4 h

$\: \: \: \: \:$

Distance = 60km / h × 1 / 4 h

$\: \: \:$

$\large\rm \red { = 15 km}$

$\: \: \: \: \:$

$\: \: \: \: \:$

For the second part of the journey :-

$\: \: \: \: \: \:$

Speed = 120 km / h ;

Time = 10 min = 1 / 2 hour

$\: \: \: \: \: \:$

Then , distance = 60 × 1 /2

$\: \: \: \: \:$

$\large\rm \red { = 30km}$

$\: \: \: \: \:$

$\: \: \: \: \:$

Therefore , the total distance covered by the car = 15 + 30

$\: \: \: \: \: \:$

$\large \rm \red { = 45km}$

$\: \: \: \: \:$

Answer 2

Question:

• A car moves with a speed of 60 km/h for 15 minutes and then 10 min with a speed of 120 km/h. Find the distance covered by the car.

Solution:

Need to find:

• Find the distance covered by the car ?

Step by step explanation:

As we know that,

• Distance = speed × time

Distance = ? km/h

Speed = 60 km/h

Time = 15 minutes

• 15/60 = 1/4 h

• Speed = Distance / time

60 km/h = Distance / 1/4h

Distance = 60 km/h × 1/4h

Distance = 15 km/h

• Therefore,The distance covered by a car for 60 km/h in 15 minutes is 15 km.

_______________________

Let us use the same formula here,

• Distance = speed × time

Distance = ? km/h

Speed = 120 km/h

Time = 10 min

• 10/60 = 1/2 h

• Speed = distance / time

120 km/h = Distance / 1/2 h

Distance = 120 km/h × 1/2 h

Distance = 60 km/h

• Therefore, The distance covered by a car for 120 km/h in 10 minutes is 60 km.

_______________________

• The total distance covered by a car = 15 + 60 = 75 km.
