The respective ratio between the speed of a car, a jeep and tractor is...
Given information:
Ratio of speed of car, jeep and tractor = 3 : 5 : 2
Speed of jeep = 250% of speed of tractor

To find:
Average speed of car and jeep together

Solution:
Let the speed of car, jeep and tractor be 3x, 5x and 2x respectively.

Given, speed of jeep = 250% of speed of tractor
⇒ Speed of jeep = 2.5 × 2x = 5x

Distance covered by tractor in 12 hours = 360 km
⇒ Speed of tractor = Distance/Time = 360/12 = 30 km/hr
⇒ 2x = 30
⇒ x = 15

Therefore, the speed of car, jeep and tractor are 45 km/hr, 75 km/hr and 30 km/hr respectively.

Average speed of car and jeep together = (45 + 75)/2 = 60 km/hr

Hence, the correct option is (a) 60 km/hr.
