speed of bus is 45 km/hr.Find(i) the distance covered in 110 mins.
(ii) the time taken to cover 150 km.

Dear Student,

Please find below the solution to the asked query:

Given : speed of bus is 45 km/hr.

We know  :  Speed  = $\frac{\mathrm{Distance}}{\mathrm{Time}}$
i ) To find the distance covered in 110 mins = $\frac{110}{60} = \frac{11}{6}$ hr  (  We know 1 hr  =  60 minutes ) .
So,

Distance covered in 110 minutes  =  45 $\times \frac{11}{6} = \frac{495}{6}$ = 82.5  km                            ( Ans )
ii )Time taken to cover 150 km = $\frac{150}{45} = \frac{10}{3} = 3\frac{1}{3} = 3 \mathrm{hr} 20 \mathrm{minutes}$                     ( Ans )
