Solution

## The correct option is D 50 kmSpeed = Distance travelled / Time of motion Therefore, Distance travelled = Speed×Time of motion In 60min, i.e., 1 h, the car travelling with a speed of 30km/h will cover 30×1=30 km If the same car travels with a speed of 40km/h for 0.5 h, the car will cover 40×0.5=20 km Therefore, the total distance travelled by the given car is, 30+20=50 km
