​

Answer 1

Answer:

Francis covers a distance of 60 km in 30 min. [ given ]

He covers distance in 1 min =60/30 =2 km.

He will time to cover a distance of 240 km =

= >total distance / distance travel in one minute = 240/2 = 120 min . Ans.

Another process = 60:30::240: x

Let the time to cover 240km be x.

Product of extreme = 60×x = 60x

Product of mean = 30×240 = 7200

=> 60x = 7200

=> x = 7200/60 = 120

=> x = 120 min.
