Answer: 3 hours and 12 minutes
Step-by-step explanation:
Case 1:
Given, total time 4 hrs and 12 minutes =4×60+12 =252 minutes and speed 44.8 km/hour = 44.8/60 km/minute
∴The distance is 252×44.8/60 = 188.16 km
Case 2:
Given, the speed 58.8 km/hour
From case 1 the distance is 188.16 km
∴The time we need is 188.16/58.8 =3.2 hours =3 hours and 12 minutes
