Question

The odometer of a car reads 12589.0 km when

clock shows the time 10:25 am. What is the

distance travelled if at 11:05 am, the odometer

reading has changed to 12619.0 km? Also calculate

the speed of the car in km/h.​

Answer 1

Answer:

Answer:

Distance = 50km

Speed = 50km/hr

Explanation:

Given:-

Initial = 47470km

Final = 47520km.

To Find:

Distance travelled = ?

Speed(km/hr) = ?

Procedure:-

Distance Travelled = Final - initial

>> Distance travelled = 47520km - 47470km

>> Distance travelled = 50km

Time Taken = 12:00 - 11:00

>> Time Taken = 1:00 hr

Calculating Speed:

So, Speed = Distance/time

Speed = 50km/1hr

Speed = 50km/hr

Answer 2

Step-by-step explanation:

solutions:l

The initial reading of the odometer of the car =57321.0 km

The final reading of the odometer of the car = 57336.0 km

The car starts at 8:30 AM and stops at 8:50 AM.

Distance covered by car = (57336 - 57321) km = 15 km

Time taken between 08:30 AM to 08:50 AM = 20 minutes = 20/60 hour = 1/3 hour

So Speed in km/min

Speed = (Distance travelled)/ (Time)

= (15km)/ (20min)

= 0.75km/min

Speed in km/h Speed = (Distance travelled)/ (Time)

= (15km)/ (1/3h)

= (15 x 3) km/ (1h)

= 45km/h
