The time taken by a person to cover 150 km was 2.5 hrs more than the time taken in the return journey. If he returned at a speed of 10km/hr more than the speed of going, what was the speed per hour in each direction?
going speed =−30km/hr, returning=−20km/hr
going speed =20km/hr, returning=30km/hr
going speed =30km/hr, returning=40km/hr
going speed =30km/hr, returning=20km/hr
If a car travels 150 km in 5 hours then its speed is
150 km/hr
30 km/hr
50 km/hr
10 km/hr
$Speed=\dfrac{distance}{time}=\dfrac{150}{5}$ $=30 km/hr$
