Question

A bus travels 350 km in 7 hours. Find the distance travelled by the bus in 9 hours given that
the speed of the bus is constant.​

Answer 1

$\large\underline\mathrm\blue{GIVEN \: :-}$

• Distance = 350 km in time = 7 hours.
• Speed of the bus is constant.

$\large\underline\mathrm\orange{TO \: FIND \: :-}$

• The distance travelled by the bus in 9 hours = ?

$\large\underline\mathrm\pink{FORMULA \: :-}$

• Speed = $\sf \dfrac {distance}{time}$
• Distance = $\sf Speed \times time$

$\large\underline\mathrm\red{SOLUTION \: :-}$

Firstly, finding the speed,

we know that, speed = $\sf \dfrac {distance}{time}$

put the values in the above formula,

Speed = $\sf \dfrac {350}{7}$

$\therefore$ Speed = $\sf 50 \: km/hr$

To find speed in 9 hours,

Distance = $\sf speed \times time$

Distance = $\sf 50 \times 9$

$\therefore \sf Distance = 450 \: km$

Answer 2

Step-by-step explanation:

$\huge \underline \bold \red{given}$

$\bold {distance \: = 350 \: km}$

$\bold{time = 7 \: hours}$

$\bold{speed = \frac{distance}{time} }$

$\bold{ \frac{350}{7} }$

$\huge \bold \red{50 \: }$

$\huge \bold{50 \times 9}$

$= \bold \green \: {450}$
