Answer 1

★ Question:

A car covers 480 km in 3 hours and 20 minutes how much time will it take to cover a distance of 80 kilometre ?

★ Answer:

distance covered by car ,d = 480 km

time taken , t = 3 hours 20 min = 3 hours + (20/60) hours = 3.33 hours

speed = ?

speed = distance / time

= 480/3.33

= 144.144 km / hr

now ;

when the distance covered by the car,d = 80 km

time ,t = ?

and speed = 144.144 km / hr

time = distance / Speed

= 80/144.144
