Answer:
[tex] \huge \mathcal{ \tt \blue{48.4 \: km}}[/tex]
Step-by-step explanation:
Distance travelled by train = 240 km in 4 hours
Distance travelled by car = 120 km in 3 hours
Distance travelled by cycle = 3 km in 1/2 hour
Total distance travelled = 240 + 120 + 3 km in 4 + 3 + 1/2 hours
= 363 km in 7.5 ( 7 1/2 ) in hours
Therefore, average here = Total distance travelled. 363 km
Total time taken = 7.5 hours
