Jonathan drove from City A to City B at a rate of 1.2 minutes per kilometer. He then drove back to City A from City B , along the same route, at 1 minute per kilometer. If he took anywhere between 3 hours to 5 hours to travel from City A to City B and between 2 hours to 3 hours on his way back, what could be the distance between the two cities?
• a)
140 kilometers
• b)
160 kilometers
• c)
200 kilometers
• d)
220 kilometers
• e)
270 kilometers

Jonathan drove from A to B at a rate of 1.2 min per km. He drove between 3 and 5 hours.
t = 3 h = 180 min which is equivalent to 150 km, (You can eliminate A, the minimum value is 150, 140 is out of range)
t = 5 h = 300 min, which is equivalent to 250 km (You can eliminate E, the maximal value is 250, 270 is also out of range)

On the way back Jonathan takes one minute to drive each km.
The trip takes between 2 to 3 hours, so he must have drove between 120 to 180 km. C and D are also out of range, the only possible answer is B
. Jonathan drove 160 km, it is the only value that belongs to both the ranges.

Can you explain this answer?
Very good qn of could be true kind
main catch is the speed ratio are 50:60 kmph
so the range is 120- 180 km
but if A-B shows the range of 150-250 km
and if you choose 140 then it ll violate A-B clause
so 140 will eliminated and 160 is considered the answer.
