A car travels 90 km in 122 hours. find the distance covered in 3 hours with the same speed.
A. 56 km
B. 72 km
C. 96 km
D. 108 km​

Answer 1

Answer:

72 km

Step by Step-----

Speed = distance /time

Speed = distance /timeSpeed = 90/(5/2)

Speed = distance /timeSpeed = 90/(5/2)= 36 km/hr

Speed = distance /timeSpeed = 90/(5/2)= 36 km/hrNow as speed remains same

Speed = distance /timeSpeed = 90/(5/2)= 36 km/hrNow as speed remains same36 = distance / 2

Speed = distance /timeSpeed = 90/(5/2)= 36 km/hrNow as speed remains same36 = distance / 2Distance = 72km
