Question

the speed of car is 60 kmph it takes 3 hour to reach it destination if speed of car increases to 90 kmph so how long it take to reach its destination??

Answer 1

speed = distance/time
distance = speed × time
d = 60×3 = 180 km
so time taken to reach the destination if the speed is 90 kmph
speed=distance/time
time = distance / speed
t = 180/90 = 2 hours
hope this helps
