Question

15) A car with the speed of 60km/hr completes a journey in 3hrs. If the journey can be
completed in 4 hrs, what can be the speed of the car? ​

Answer 1

Answer:

45 km/h

Step-by-step explanation:

Speed of car = 60 km/h

Time taken = 3 hours

Distance = (60×3) km = 180 km

New time taken = 4 hours

Hence, new speed = (180/4) km/h = 45 km/h

Answer 2

Answer:

distance = speed ×time

180 = 60 km/hr×3hr

speed =distance /time

therefore,

180 /4 =45km/hr
