Speed, Time and Distance
A man has to cover a distance of 753 km in 12 hours. If he covers two-third of this distance in 2/3 of the time, then what should his speed (in km/hr) be to cover the remaining distance in the time left?
Mr. W travelled 370 km, 390 km and 720 km at speeds of 37 km/hr, 5 km/hr and 8 km/hr, respectively. Find his average speed in km/hr. (Note: Speed typo corrected for logical accuracy based on calculation)
