A train leaves at 11.15 and arrives at its destination at 12.23. If the train travelled 95 km, what was it's average speed in km
xxMikexx [17]

Answer:

Average speed v = 83.8 km/h

Step-by-step explanation:

Given;

Distance travelled = 95 km

Time taken t = 12.23 - 11.15 = 1 hour 8 minutes

t = 1 + 8/60 hours = 1.133 hours.

Average speed v = distance travelled/time taken

substituting the values;

v = 95 km ÷ 1.133 hours

Average speed v = 83.8 km/h

ANEK [815]

Answer:

BE = 39/5 or 7.8

Step-by-step explanation:

As <ABC = <DBE trigonometric function is angle BAC and angle BED

so sin (<ABC) = sin(<DBE) and AC and BC , BD and BE

so AC/AB = DE/BE = 13/BE = 5/3

So now we cross multiply

BE = 13 × 3 over 5

13 × 3 = 39

and over 5 means

39/5 = 7.8
