Respuesta :
Answer: D.) 102 kilometres per hour
Step-by-step 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.
Answer:D
Step-by-step explanation:
34km per 20 minutes
Since 60seconds make 1minute
60minutes make 1 hour
Therefore,
34mkm*3:20*3
102km:1 hour
