Question

a car travels 130 km in 2 1/2 [2 and a half hour] a.find the time required to travel 240 km. b.find the distance in 3 hours

Answer 1

The car travel 130km in =2 1/2=5/2 hrs.
∴, the car travel 1km in =(5/2)/130 hrs.
∴, the car travel 240km in=(5×240)/(2×130)=60/13 hrs=4 8/13 hrs.
In 5/2 hrs. the car travels =130km
in 1 hr the car travels=130/(5/2)km
∴, in 3hrs. the car travels=(130×2×3)/5=26×6=156km
