Question

A Car travels 130km in 2 1\2 hours find time required to travel 240km and find the distance travelled in 3 hours ​

Answer 1

Explanation:

Answer

1st case

distance travelled by a car =130 km

time= 2 1/2 hours= 5/2hours

speed= distance/time=130/5/2= 130×2/5=26×2

= 52km/hr

2nd case

speed =52km/hr

distance = 240 km

time= distance/ speed = 240/52=120/26=60/13

= 4 whole 8/13

= 4 8/13

3rd case

time= 3 hr

speed= 52km/hr

distance = speed× time

distance = 52×60/13=4×60=240km

distance =240km

hope it helps
