Question

The odometer of a moving car reads 4820.0 km when the clock shows the time 08:30 AM. At 08:50 AM, the odometer reading shows 4864.0km? What is the speed of the car in km/h during this time?​

Answer 1

SOLUTION

The odometer of a moving car reads 4820.0 km when the clock shows the time 08:30 AM. At 08:50 AM, the odometer reading shows 4864.0 km

TO DETERMINE

The speed of the car in km/h during this time

EVALUATION

Here it is given that the odometer of a moving car reads 4820.0 km when the clock shows the time 08:30 AM.

At 08:50 AM, the odometer reading shows 4864.0 km

The distance travelled

= 4864.0 km - 4820.0 km

= 44 km

Time taken

= 8:50 AM - 8:30 AM

= 20 minutes

$\displaystyle \sf{ = \frac{20}{60} \: \: hour }$

$\displaystyle \sf{ = \frac{1}{3} \: \: hour }$

Hence the required speed of the car

$\displaystyle \sf{ = \frac{44}{ \frac{1}{3} } \: \: km/h }$

$\displaystyle \sf{ =(4 4\times 3) \: \: km/h }$

$\displaystyle \sf{ = 132 \: \: km/h }$

Answer 2

Given : The odometer of a moving car reads 4820.0 km when the clock shows the time 08:30 AM.

At 08:50 AM, the odometer reading shows 4864.0km  

To Find :  the speed of the car in km/h during this time ​

Solution:

Distance covered = 4864.0 - 4820.0  = 44 km

Time =  8 : 50 AM - 8 : 30 AM  = 20 mins

60 mins = 1 hr

=> 20 mins = 20/60  = 1/3  hrs

Speed = Distance / Time

=> Speed = 44 / (1/3)

=> Speed = 132  km/hr

speed of the car in km/h  = 132 km/hr
