How much time would it require if speed is 120 km/h? How much time would a car
travelling at the speed of 50 km/h require to reach the city A from the city B?​

Answer 1

Answer:

1) 1.5 hrs 2) 3.6 hrs

Step-by-step explanation:

distance from a to b = 90*2 km = 180 km

for 120 km/h time = (180/120) hrs = 1.5 hrs

for 50 km/h time = (180 / 50) hrs = 3.6 hrs
