Question

How much distance will a car cover in 45 minutes if it travels at a speed of 45 km per hour​

Answer 1

• Distance travelled by car is 33.75 km .

Step-by-step explanation:

To find :-

• Distance travel by car.

Solution:-

Given that,

Time taken by car is 45 mins

So, 45/60 h = 0.75 h

Total time taken is 0.75 hours.

Speed of car is 45 km/h.

We know that,

Distance = Speed × Time

• SI unit of Distance is km.

• SI unit of Speed is km/h.

• SI unit of Time is hour.

So,

➝ 0.75 × 45

➝ 33.75

Therefore,

Distance travelled by car is 33.75 km .

Answer 2

$\bf \huge \{ answer \}$

How much distance will a car cover in 45 minutes if it travels at a speed of 45 km per hour

$\bf \large \ \ ANSWER \underline \ \ \\ \ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Let speed is X kmph

Time is 45 mts =3/4 hr

Distance is 3X/4 km

Reduced speed is X-8 kmph

Time is 49.5 mts

Distance is (X-8)(49.5/60)

Distance is same .

3X/4=(X-8)(49.5/60)

3X=(X-8)(198/60)

180X=198X-1584

18X=1584

$\bf \pink{X=88}$

Distance between A and B is (3/4)*88=66km
