Question

29.An athlete completes a race in 16 minutes at a speed of 35 km per hour. Find the time
taken by the athlete to complete the race running at a speed of 32 km per hour.​

Answer 1

Step-by-step explanation:

time taken by an athlete to complete race = 16 min = 16/60 hr = 4/15 hr

Speed of an athlete = 35 km/hr

Distance = speed × time

= 35 km/hr × 4/15 hr

= 28/3 km

Now, Speed of an athlete = 32 km/hr

time = Distance ÷ speed

= (28/3) ÷ 32

= 7/24 hr
