find the distance travelled by the train between 11.50 am and 12.30 pm from the data given below​. time 11.30 12.00 12.10 12.20 12.30 kmph48.2 70 82.6 85.6 78.4​

Answer 1

Step-by-step explanation:

Solution 1:

I think 11:30 to 12:00 the speed was 70

1150 -1200 = 70 / 6 = 11+(2/3)

1200 - 1210 = 82.6/6=13+(4.6/6)

1210-1220=85.6/6=14+(1.5/6)

1220-1230=78.4=13+(0.4/6)

adding the kilometres up

11+2/3+13+4.6/6+14+1.5/6+13+0.4/6

51+2/3+4.6/6+1/4+4/60

51+(40+46+15+4)/60

(3060+105)/60

3165/60

52.75 kms
