According to question , Time taken by B to finish 1500m race = \(\frac{1500}{6}\) = 250 sec Given that :- A gives a start of 10 sec to B So , Time taken by A to finish the race = 250 - 10 = 240 sec As 1 minute = 60 sec So , 240 sec = 4 minutes . Hence , the time taken by A to finish the race is 4 minutes . |
