Question

Player z runs at a speed of 35km/hr and compelets a race in 16 minutes.If player H's speed is 32km/hr in how much time will he compelete the race

Answer 1

Answer :
Given
Player z runs at a speed of 35km/hr and compelets a race in 16 minutes

We know

distance = Speed $\times$ Time
here Speed = 35 km / hr
time = 16 min = $\frac{16}{60}$ hr
So,
Distance = 35 $\times$ $\frac{16}{60}$ = 7 $\times$ $\frac{16}{12}$ = $\frac{28}{3}$ km

Now
speed of player H = 32 km/ hr
and distance = $\frac{28}{3}$ km

and we know

Time = $\frac{Dis\tan ce}{Speed}$
So,
Time taken by Player H = $\frac{{\displaystyle \frac{28}{3}}}{32}$ = $\frac{28}{96}=\frac{7}{24}$ hr

So time taken in minutes = $\frac{7}{24}\times 60$ = 17.5 minutes ( Ans )
