Question

The speed of a train is 60 1/2km /h . how much distance the train will travel in 10 1/2 hours 45/2

Answer 1

Speed of the train = 60 × 0.5 =30 km/h.

The time is 10 × 0.5 = 2 hrs. + 45×0.5 = 22.5 minutes.

0.5 minutes = 0.5×60 = 30 seconds.

The total time will be 2 hrs 22 min 30 sec.

So, the total distance traveled will be

Distance = Speed × Time.

For 2 hrs:— 30×2 = 60 km

For 22 minutes:— 30 × 22/60hrs = 11 km

For 2 seconds:— 30 × 2/3600 = 0.1666 km.

Adding all these we get,

60+11+0.16666 = 71.166666 km

Answer 2

Step-by-step explanation:

10527/16 or 657.9375 because 21/2+45/2×1/60=21/2+3/8=84+3/8=87/8= 87×121/8×2= 10527/16or 657.9375
