Question

aka takes 6 hours to complete a journey at speed of 72 km / hrs how long will another ka take to complete the same journey if its speed is 15 m/sec​

Answer 1

Answer:  8hr

Step-by-step explanation:

first we have to find distance so formula d = speed × time then d = 72×6 then d = 432 now the second speed is 15m/s so we have to convert it into kilometre per hour then (15×18)/5 then 54km/h now we have to find time so time = distance/ speed, then time = 432/54, and then 8 hours is your answer

Answer 2

Step-by-step explanation:

distance = speed × time

distance = 72× 6 = 432km

now we need to find time

first convert km into meters we get 432000m

432000 = 15 × time

time = 28800 seconds = 480 minutes = 8hrs
