Answer 1

SOLUTION

GIVEN

A school bus travels distance of 30 km in 1 hour

TO CHOOSE THE CORRECT OPTION

The time it will take to travel distance of 90 km.

• 2 hours

• 3 hours

• 4 hours

• 9 hours

EVALUATION

SOLVE USING RULES OF THREE

Here it is given that a school bus travels distance of 30 km in 1 hour

We have to determine the time it will take to travel distance of 90 km

$\sf{Distance ( Km) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: Time ( Hour) }$

$\sf{ \: \: \: \: \: \: \: 30 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:1 \: }$

$\sf{ \: \: \: \: \: \: \: 90 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:? \: }$

Here as the distance increases so the required time will increase

Therefore Distance and Time are in direct proportion

Hence the required time

$\displaystyle \sf{ = 90 \times \frac{1}{30} \: } \: \: \: hour$

$\displaystyle \sf{ = 3\: } \: \: \: hour$

FINAL ANSWER

The time it will take to travel distance of 90 Km is 2 hours
