Rate downstream =1x 60km/hr = 6 km/hr.10
Rate upstream = 2 km/hr.
Speed in still water =1(6 + 2) km/hr = 4 km/hr.2
 Required time =5hrs = 11hrs = 1 hr 15 min
Rate upstream = 2 km/hr.
Speed in still water =1(6 + 2) km/hr = 4 km/hr.2
 Required time =5hrs = 11hrs = 1 hr 15 min

Rate downstream =(1/10×60)km/he=6km/hr
Rate upstream = 2 km/hr
Speed in still water =1/2(6+2) km/hr=4km/hr
required time=5/4hrs=1¼hrs=1 hr 15min
hope it helps you :-)
pls mark it as the brainliest
thank you.
