Question

a journey takes 4 hours 30 minutes at a speed of 60km/h.how long will the same journey take place at a speed of 15km/h

Answer 1

hello friends.....

solution:-
let the distance covered in the journey = x km

we know that
distance = speed × time
here.
speed = 60 Kmph
and time = 4h30m = 4.5 h


=> distance ( x) = speed × time =
60 × 4.5 = 270 km

how long time it will take for the same journey at a speed of 15km/h .

here ,
speed = 15 Kmph
and distance ( x) = 270 km

then .
time = distance / speed
= 270/15 = 18 hours answer
