Question

For a car that travels 34 kilometers in 20 minutes, determine the rate at which the car travels.

A.) 34 kilometers per hour
B.) 54 kilometers per hour
C.) 68 kilometers per hour
D.) 102 kilometers per hour

Answer 1

Answer:D

Explanation:

34km per 20 minutes

Since 60seconds make 1minute

60minutes make 1 hour

Therefore,

34mkm*3:20*3

102km:1 hour

Answer 2

Answer: D.) 102 kilometres per hour

Explanation:

The car travels 34 kilometres in 20 minutes, to find the rate at which the car travels in kilometres per hour, we find convert the time taken (given in minutes) to travel this 34 kilometres to hours.

By doing this, 20 minutes = (20/60) hours = 1/3 hours.

Now to determine the rate, the motion Formula is given by:

Rate of travel = distance/time.

Rate = 34 / (1/3)

Rate = 34 * 3

Rate = 102 kilometres per hour.
