Question

odometer of a car reads 1560 km while starting from a point and 1670 km when its returns after 5 hours. what is
A)the distance travelled? B) speed of the car?
C) convert the speed in S.I. unit​

Answer 1

Solution

Initial Kms (a) = 1560 Km

Final kms (b) = 1670 Km

Total Kms covered = ( b - a) = 1670 - 1560 = 110 km

Total time taken = 5 hours

Speed of car = $\dfrac{Distance}{Time}$

= $\dfrac{110}{5}$

= 22 Km/hour

In SI unit m/sec

Speed in MS = 22 * $\dfrac{5}{18}$

= 110÷18

= 6.1 m/sec

Answer 2

Answer:

Solution

Initial Kms (a) = 1560 Km

Final kms (b) = 1670 Km

Total Kms covered = ( b - a) = 1670 - 1560 = 110 km

Total time taken = 5 hours

Speed of car = {Distance}{Time}/

Time=5

distance=110

= 22 Km/hour

In SI unit m/sec

Speed in MS = 22

18

5

= 110÷18

= 6.1 m/sec
