Answer 1

Question :

A car travels at an average speed of 60 km / h for 15 minutes. How far does the car travel in 15 minutes?

A) 4.0km

B) 15km

C) 240km

D) 900  km

Answer:

B) 15 km.

Given:

Speed of the car = 60 km/h.

Time = 15 minutes.

To find:

The distance travelled by the car in 15 minutes.

Explanation:

1 hour = 60 minutes.

Hence,

In 60 minutes the car travels a distance of 60 km.

∴ In 1 minute the car travels a distance of (60÷60) km

                                                                    = 1 km.

∴ In 15 minutes the car travels a distance of _

(1×15) km.

⇒ 15 km.

∴ In 15 minutes the car travels a distance of 15 km.

Hence,

option (B) 15 km, is the right answer.
