Question

A bus travels with a speed of 40 km/hr in the 1st hour and 80 km/hr in the 2nd. What is the total distance covered by the car in the two hours?

• A. 40 km
• B. 120 km
• C. 80 km
• D. 160 km

Answer 1

The correct option is B 120 km

Distance= speed $\times$ time
Distance travelled in the 1st hour is:
Distance = 40 $\times$ 1
= 40 Km
The distance covered in the 2nd hour is:
Distance = 80 $\times$ 1
= 80 Km
The total distance is:
40 km + 80 km = 120 km
