Question

A car with the speed 60km per hr complete a journey in 3 hrs.If the journey is to complete in 4 hrs. what can be speed of th car

Answer 1

as speed = distance / time thus in first case when speed =60 km/h and
time =3 h thus the distance = 60×3 = 180 km
thus if we take t = 4h
distance = 180 km
speed will be 180/4 km /h
=45km / h
hope it will help you

Answer 2

Step-by-step explanation:

speed =distance/time thus in first case when speed =60km/hour

and,

Time =3hours then the distance

60×3 = 180km

thus if we take the time is 4hour.

Distance = 180km

speed will be 180/4km/hr

= 45km/hour
