Question

Sima rides her bicycle at 12 km per hour. If she rides it for three and a half hours, total distance covered by her is km.

• A. 36
• B. 42
• C. 12

Answer 1

The correct option is B 42

Time for which Sima rides her bicycle = Three and a half hours
Speed at which Sima rides her bicycle = 12 km in one hour
Distance that Sima will cover in half hour = 12 $÷$ 2
= 6 km
Total distance that Sima will cover in three and a half hours = 12 + 12 + 12 + 6
= 42 km
