• A car covers 110 km in 4 hours. How many kilometres will it cover in 18 hours?

$\huge {\bf{\orange{\mathfrak{Answer:-}}}}$

• A car travels 110km in 4 hours.

• Let's find the number of km that the car travelled in 1 hr.

• $\therefore{\textsf{Kilometers \: \: travelled \: \: by \: \: the \: \: car \: \: in \: \: 1 hr \: \: = \: \: }\frac{110}{4}}$

• $\frac{110}{4} \: \: = \: \: 27.5$

• $\boxed{\therefore{\textsf{In \: \: 1hr \: \: the \: \: car \: \: travels \: \: 27.5km/hr}}}$

• Now, Distance travelled by the car in 18hrs =

• $\textsf{27.5 \: \: * \: \: 18 \: \: = \: \: 495 \: km/hr}$

$\huge{\bf{\red{\mathfrak{Conclusion:-}}}}$

• $\boxed{\therefore{\textsf{Distance \: \: travelled \: \: by \: \: the \: \: car \: \: in \: \: 18hrs \: \: = \: \: 495 \: km}}}$

Answer 2

Given,

• A car covers 110 km in 4 hours.

To Find,

• Distance Travelled By Car in 18 hours.

Solution,

Let's,

The Distance travelled by the Car

= X

In First Case Where,

Distance = 110 km

Time = 4 hours

The Rate Of Change in Distance

= Distance/Time

= 110/4 kmph

In Second Case Where,

Distance = X

Time = 18 hours

The Rate Of Change in Distance

= Distance/Time

110km/4h = X/18h

110km/4h × 18h = X

495km = X

Required Answer,

If,

A Car covers 110 km in 4 hours,

Then,

The Car covers 495 km in 18 hours.
