Question

A main covers 31/»50 km in 3.5 hp what is the distance covered by it in i hour?​

Answer 1

Answer:Solution 1:

Given: Distance= 51 km

Time= 3 hours

Therefore Speed = \frac{Dis\tan ce}{Time}

= \frac{51}{3}

=17km/h

Now,

Time= 30 minutes = \frac{30}{60}h=\frac{1}{2}h

Speed=17km/hr

Distance travelled = Speed\times Time

=17\times\frac{1}{2}=8.5\ km
