A car runs 20 km. using 1 litre of petrol. How much distance will it cover using 2 $\frac{1}{2}$ litres of petrol.

Answer:_______________

A car runs 45 km. using 1 litre of petrol. How much distance will it cover using 2 $\frac{3}{4}$ litres of petrol.

Answer: 123.75 km

SOLUTION 1 :

Given :

Distance covered by the car = 45 km (1 litre of petrol)

Distance covered by 2 $\frac{3}{4}$ litres of petrol = 2 $\frac{3}{4}$ x 45

= $\frac{11}{4}$ x 45

= $\frac{(11x45)}{4}$

= $\frac{495}{4}$

=123.75 km

A car runs 35 km. using 1 litre of petrol. How much distance will it cover using 3 $\frac{2}{4}$ litres of petrol.

Answer: 122.5 km

SOLUTION 1 :

Given :

Distance covered by the car = 35 km (1 litre of petrol)

Distance covered by 3 $\frac{2}{4}$ litres of petrol = 3 $\frac{2}{4}$ x 35

= $\frac{14}{4}$ x 35

= $\frac{(14x35)}{4}$

= $\frac{490}{4}$

=122.5 km

A car runs 50 km. using 1 litre of petrol. How much distance will it cover using 3 $\frac{3}{2}$ litres of petrol.

Answer: 225 km

SOLUTION 1 :

Given :

Distance covered by the car = 50 km (1 litre of petrol)

Distance covered by 3 $\frac{3}{2}$ litres of petrol = 3 $\frac{3}{2}$ x 50

= $\frac{9}{2}$ x 50

= $\frac{(9x50)}{2}$

= $\frac{450}{2}$

=225 km

A car runs 20 km. using 1 litre of petrol. How much distance will it cover using 4 $\frac{1}{2}$ litres of petrol.

Answer: 90 km

SOLUTION 1 :

Given :

Distance covered by the car = 20 km (1 litre of petrol)

Distance covered by 4 $\frac{1}{2}$ litres of petrol = 4 $\frac{1}{2}$ x 20

= $\frac{9}{2}$ x 20

= $\frac{(9x20)}{2}$

= $\frac{180}{2}$

=90 km

A car runs 25 km. using 1 litre of petrol. How much distance will it cover using 3 $\frac{2}{2}$ litres of petrol.

Answer: 100 km

SOLUTION 1 :

Given :

Distance covered by the car = 25 km (1 litre of petrol)

Distance covered by 3 $\frac{2}{2}$ litres of petrol = 3 $\frac{2}{2}$ x 25

= $\frac{8}{2}$ x 25

= $\frac{(8x25)}{2}$

= $\frac{200}{2}$

=100 km

A car runs 55 km. using 1 litre of petrol. How much distance will it cover using 4 $\frac{1}{2}$ litres of petrol.

Answer: 247.5 km

SOLUTION 1 :

Given :

Distance covered by the car = 55 km (1 litre of petrol)

Distance covered by 4 $\frac{1}{2}$ litres of petrol = 4 $\frac{1}{2}$ x 55

= $\frac{9}{2}$ x 55

= $\frac{(9x55)}{2}$

= $\frac{495}{2}$

=247.5 km

A car runs 55 km. using 1 litre of petrol. How much distance will it cover using 3 $\frac{3}{2}$ litres of petrol.

Answer: 247.5 km

SOLUTION 1 :

Given :

Distance covered by the car = 55 km (1 litre of petrol)

Distance covered by 3 $\frac{3}{2}$ litres of petrol = 3 $\frac{3}{2}$ x 55

= $\frac{9}{2}$ x 55

= $\frac{(9x55)}{2}$

= $\frac{495}{2}$

=247.5 km

A car runs 45 km. using 1 litre of petrol. How much distance will it cover using 4 $\frac{1}{4}$ litres of petrol.

Answer: 191.25 km

SOLUTION 1 :

Given :

Distance covered by the car = 45 km (1 litre of petrol)

Distance covered by 4 $\frac{1}{4}$ litres of petrol = 4 $\frac{1}{4}$ x 45

= $\frac{17}{4}$ x 45

= $\frac{(17x45)}{4}$

= $\frac{765}{4}$

=191.25 km

A car runs 30 km. using 1 litre of petrol. How much distance will it cover using 4 $\frac{3}{2}$ litres of petrol.

Answer: 165 km

SOLUTION 1 :

Given :

Distance covered by the car = 30 km (1 litre of petrol)

Distance covered by 4 $\frac{3}{2}$ litres of petrol = 4 $\frac{3}{2}$ x 30

= $\frac{11}{2}$ x 30

= $\frac{(11x30)}{2}$

= $\frac{330}{2}$

=165 km

10)

A car runs 20 km. using 1 litre of petrol. How much distance will it cover using 2 $\frac{1}{2}$ litres of petrol.

Answer: 50 km

SOLUTION 1 :

Given :

Distance covered by the car = 20 km (1 litre of petrol)

Distance covered by 2 $\frac{1}{2}$ litres of petrol = 2 $\frac{1}{2}$ x 20

= $\frac{5}{2}$ x 20

= $\frac{(5x20)}{2}$

= $\frac{100}{2}$

=50 km
